We were looking for a gluten free meal and discovered Diablo Burger. Hard to find but worth it! My husband said it was the best GF bun (muffin) he has ever had. Service was great and we sat in the outdoor covered patio with our dog. Highly recommend this place! read more

Very disappointed and I don't understand how they have 4 stars. Someone recommend this place since we are visiting Flagstaff. The service was decent nothing amazing. The food was mediocre at best. I ordered the Big Daddy Kane (pickles, sharp cheddar, bacon, and thousand island) medium and it had noooo flavor at all whatsoever. It was so bland and just not good. The burger was a super thick patty and even cooked medium was kind of dry. The fries were salty and okay. Also let's not forget that the burger was $15. I ordered the burger and a root beer and it was $21. Outrageous prices for a mediocre burger. The inside is small and there are a few tables outside. I would not recommend or be back. read more

Diablo Burger - Big Daddy Kane. Not good. - Burgers Near Me - Flagstaff, Arizona

This is a golden spot. You cannot miss Diablo burger when you come to Flagstaff. We saw people raving about it in a couple of YouTube videos and this was our first stop here. The burgers are made with English muffins- which I have never seen and it's truly a game changer. The burgers are neatly constructed and I was able to eat the whole burger without any of it sliding out. The blackboard special had a carrot/jicama slaw and grilled poblano in it- goodness, I am drooling thinking about it right now. The wrigley is also very well made and definitely a new take on your classic Swiss+mushroom burger. The frites are very crispy and unique and I couldn't stop eating them! If you have just one meal in Flagstaff, this is the spot you should come to. read more

Passing through Flagstaff on my way to Florida and decided to eat here. I almost miss it completely because it is a little off the beaten path. The burger's are juicy and made with grass-fed and ethically raised beef, which is amazing. There are just a few personal reasons I couldn't give this a 5 star review. First, I am not a fan of super thick burgers and this one was huge. I also only like my burgers well done and they strongly discouraged my from getting it well done since they are super low in fat and they said it would be really dry. I ordered medium well and it was still very pink in the middle. The other reason I was not 100% happy is the seating arrangements. Super small dining area and shared seating on high top stools, plus the heat was really hot inside the building. Overall I would recommend this place if you like big juicy burgers that are super flavorful and don't mind take out or sharing your table! read more

Diablo Burger - The Cheech Burger - Burgers Near Me - Flagstaff, Arizona

Cool place and the quality is definitely good, but the burgers feel like they could use a little seasoning or a smash to it to get some extra flavor. The fries are also good and a generous portion, the herbs on ours was a little heavy though and not pleasant, to me anyways, when I'd get a bite of what I believe is fennel. I could overlook these things and come back if it wasn't for the long wait, what I thought by other ordering lines might be 20-30 minutes and ended up being an hour. Not because the line is long but because they seem to just not care. The girl taking orders meanders around doing other things and has a idgaf if you've been waiting attitude. She's also delivering drinks out to your table and delivering food and I get if they're short staffed, but maybe pick up the pace, and if that's just how they run things there and is normal, it's not an efficient process at all. Is it worth trying, sure the quality is great, but if there's a line be prepared for a longer than you expect wait. And if you're already hangry, do yourself a favor and go somewhere else, and save this place for another day lol. read more

This is a go-to place whenever I'm in Flagstaff, especially after a good hike! The burgers are a little pricey but they are huge and the English muffin buns are nice. Fries are always delicious and the beer selection is a good mix of local stuff. The patio seating is really nice and spacious. read more

Burger was one of the best ones I've ever eaten, chair was one of the worst I've ever sat in, so lost a star for the uncomfiness. Service didn't seem like something this place is known for, but there was a blizzard outside so I factor that in. As for ambiance, I don't think that's the focus of this place, it was very cramped but there was an ambient peppery burger smell which was good, and the meat scent competed with the terrible chair for which one would win. In the end it was a tie between those two, but it doesn't even matter because the burger itself was so good. So good that it was worth walking a block in a blizzard to go eat it. Idk I'm tired. read more

Prices are absurdly expensive, especially for a slider. The inside seating is very cramped but they have tables outside. Pretty sure my boyfriend and I's sliders were raw, we couldn't finish them. We left extremely disappointed because we heard a lot of great things about this place. read more

Diablo Burger - Blutarsky Burger - Burgers Near Me - Flagstaff, Arizona

Quite possibly the best restaurant burger I've ever had. The entrance with its wind tunnel was a bit odd, but once I was inside I was greeted with a friendly hello and a smile. Ordering was easy, and the person helping me knew the answers to my questions. My food was cooked to order, and I had enough time to go next door to wash my hands, come back, and sit for a few min before it arrived. I couldn't have the English muffin bun (dairy allergy). They offered their gluten free bun, but I opted for a lettuce wrap instead. The burger was super juicy and this was messy, but not as crazy as I worried it might be, lol. My burger was cooked perfectly and was seasoned DELICIOUSLY. All caps deserved. Man, that was a good burger! The quality of their beef really shines through. Then the fries. The fries!!! Oh my yum. I loved how fresh they were, and the rosemary on them. I was stuffed, and for about $17. read more

Diablo Burger - Big Daddy Kane Burger w/ extra patty - Burgers Near Me - Flagstaff, Arizona

Great burgers and fries. Outdoor dining is ok. Neat historic in town. Service was good. Source many local ingredients.

Diablo Burger has been on my bucket list for a while. Finally, I was in town and made the time to have lunch. Nearly all the ratings where off the chart; I was looking forward to the "best burger." First, their burgers are cooked to what they call "medium rare"; which was fine with me. Knowing that when I ordered, it didn't bother me that I wasn't asked about temperature which they definitely should be asking. My burger arrived more on the rare side than medium. The middle of burger was raw ground beef. I wasn't going to say anything until another customer sitting at the same table complained about her burger being raw in the middle. Immediately, the server became argumentative. Finally, I spoke up and said, yes, you are serving raw beef today. The argument continued with me and I asserted that I know how to cook by temperature and this burger wasn't temperature checked in the middle before pulling from the grill. They are very defensive of their idea of medium rate. Be warned, unless you state firmly when ordering that you want medium, medium well or well done, you will be served what they consider medium rare. Expect raw ground beef. I' m not a fan of a burger served on an English muffin; but that is what they offer. The beef is high quality and if cooked to a proper medium rate (135F), I'm sure it would be delicious. Know that is a 6oz (before cooking) burger. Fries - They are seasoned with thyme, oregano, lavender and salt. While they were perfectly cooked, it's not to my liking to have lavender fries. Overall, at $50 for two burgers, with fries, a salad and two drinks is overpriced. I will not be going back. @Diablo - if you find yourself arguing with a customer, you've already lost. Not only are you wrong for arguing, every customer within ear shot hears you. The customer may not always be right, but if you do your job correctly, they will always be your customer. read more

We drove to Flagstaff from Roseville, CA today. After the 11 hour drive a burger is just what I needed. I gotta say - excellent burgers! My wife had the Spring Picnic Burger with grilled peaches, cream cheese, honey, & a patty. She loved it! I had the Marilyn & my sister had the Blake. The fries are seasoned with rosemary and are amazing too! Cute little place in downtown. Best seating is outdoors on the patio and seating inside is limited. Service was super friendly & helpful. This place rocks the burgers & check out their specialty sauces as well. Nice little gem in Flagstaff! read more

Located in the middle of downtown. Burger was smaller than expected but still tasty. They ask how you want it cooked and you can eat inside or outside. Slightly pricier than I expected. Fries were very good and ranch was even better. read more

We were visits when it was cold and traveling with a dog. Patio was heated and covered. It was adequate. Burgers on an English Muffin tasty. Service a bit grumpy- but hey who wants to work the holidays? read more

Pretty disappointing and not what we remembered. We lived in Flag for more than 5 years and used to love Diablo. After moving back to Northern Arizona, we decided to come back on a day trip to Flag and have lunch at (what used to be) one of our favorite lunch spots. Long story short, it was a disappointing use of $70. We had three burgers w/fries and realized that the grass fed burgers we can get at our local farmer's market are just as good (if not better) at a fraction of the price. The staff seemed less friendly than we remembered too. Sadly, we don't have plans to go back. read more

The worst service in Flagstaff! I visited the city for the first time and because I love hamburgers we tried this place. Not only was the burger just ok, the girl at the register (white girl with wavy brown hair wearing glasses) was rude and uninviting. Not sure what her problem was but she should not be the person greeting guest nor taking orders. Horrible service and that's enough to keep me from returning. Avoid this place! Everywhere else in the city was great. read more

The short of it is that this is an outrageously priced ($16) 6oz burger on an English muffin served with fries. I knew this was going to be a child's portion so I also ordered the grilled cheese for $12.75 (which also came with fries). I find it kind of misleading that the header photo on their website *appears* to be a full-sized burger on a full-sized bun. The burger was flavorful but when the bun is so thin that your hands get burned by the sizzling beef patty, that's where I'd go back to the drawing board. The concept makes no sense to me aside from that people would complain about the burger size if they were served on full-sized buns or even the ever-shrinking brioche buns you find at grocery stores. The grilled cheese was overloaded with vegetables. Makes for a weird mouth feel that is way too mushy. Helped fill me up, though. Fries were meh, consistency not impressive at all while seated outside. Both too thin to be enjoyable in one way and too thick to be enjoyable in the other way. You'd have a really hard time convincing me to pay $6.25 for a basket of fries in Arizona. Ultimately, this locally-sourced pitch feels like virtue signaling for no reason and with no measurable benefit to consumers. If it means the prices are literally doubled compared to Mama Burger's, and I still get asked to leave a tip after standing in line at a counter for 20 minutes, I find it to be more of an insult that anything. read more

Very rude and disorganized front of house - extremely over priced. Tourist trap, not a welcoming spot for locals because they are renowned for being over priced, under staffed, crowded and frequently rude. Certain staff give the impression they don't care about the customer experience . At this price point that matters. There's a lot of great burger places in Flag. Recommend skipping this one especially if they are busy. I once waited in line only to have the hostess/cashier stop taking orders as soon as it was my turn. At a minimum she could have put a sign out and ended the line before folks waited 45 min - an hour to order only to be turned away. Also, everyone can hear and see the way you are speaking to your customers. read more

If they didn't have an English muffin bun this would be 5 stars, but the bun ruins it. English muffins are hard to bite through, which means all the juices run out of the burger and all the toppings fall out. This is a shame as the burger itself is great and there is a nice menu of interesting topping combinations. The fries are excellent too. Please, please get rid of this English muffin bun, or at least offer an alternative with a regular or brioche bun. read more

terrible price to food ratio. 20 dollars for a burger the size of a silver dollar. mediocre at best.

My husband and I stopped here for a hamburger. A friend pre-warned me that Diablo makes thick burgers that are rarer than expected. At most restaurants I order a burger cooked to medium. At Diablo I ordered a well- done burger, and it had the right ("medium") amount of pinkness inside, with a well-done outside. Perhaps the restaurant is unable to adjust the temperature of their grill to accommodate different requests for doneness. It all worked out. My burger was very good. It's nice to have a hamburger thicker than the typical thin patty. We got fries, and they were good. The ambiance of this place is rather stark and fast-foodish. We sat inside on tractor-seat bar stools at a high table. The stools offer little back support. This is not a comfy spot where I would want to linger. The restaurant's plan is probably for customers to eat and leave. There is additional seating at on outdoor uncovered patio. Those tables appear to be normal height picnic tables with long picnic benches. It was dark when we visited so I didn't get a good look. read more

Have an urge for a delicious burger and need a gluten-free bun? This is the place to have your carnivorous need met and then it comes with delicious fries! So many choices for burger add-on: type of cheese, bacon, hot peppers, etc and then in your basket will be tomato, lettuce and pickle spear. They recommend your burger be medium rare and that was perfect for cooking this lean burger! Yes, there are the regular buns for your burger and choices of drink: beer, soda and wine. With beer in hand you need to stay within a certain section of the outdoor patio, but if you are beer-free there is plenty of additional outdoor space. Enjoy... read more

Seating policy is crap. You have to order first and you are not guaranteed a seat after that. I tried to sit at the bar with 4 people. They said we had to order first to sit down. While we were deciding, someone took the seats by just ordering a beer. LameAF. Overpriced. Bad atmosphere. Not worthy of the name Diablo. GFYS read more

Gave it a try, pretty good, got it to go which was not the best choice due to cooling off too much before i got back to my motel, would have been better if I had it there.

The burgers are good, not great and were small since they use an english muffin for a bun. The price doesn't justify the quantity but at least they give you a lot of fries. I'm not a fan of the seating arrangement at the moment which is only outside. There is 4 tables that are around 10 foot long that you share with other people. read more

Came highly recommended as one of the best burgers in Flagstaff. Can't comment on the other food but my particular hamburgers was average at best. Meat was ok, buns were English muffins with the business icon branded on it. Bacon on my burger was disappointing and akin to a fast food flimsy peace, green hatch chili on my burger was pre-chopped hatch from a can. Burgers lacked fresh food items for the price. The service was great, server was attentive and patient with us as 1st timers. The ambiance was good as we sat in the front patio w/ our dog. For 1st timers, we walked a few laps up and down the street to finally find the location behind shops/restaurants on Leroux street, in an alley. I don't mind the monetary standard at eating establishments, but it should match a good, wholesome product...Which didn't. read more

I got the cheech burger and seltzer. The burger was great but the bun couldn't hold everything up and ended up getting soggy and breaking down. The fries had rosemary which was good. The seltzer wasn't great. We also had to wait 30 min in line but a line that wasn't that long.. it took forever to get our order in read more

Stumbled upon this place when every place we called for dinner in Flagstaff had a 45-75 minute wait on a Monday! Great grass-fed burgers and fries. Patties were cooked medium. I loved the English muffin concept. However, it does make the burger smaller than usual, so it is a little pricey. My husband (who has a big appetite) could have enjoyed two burgers. My big daddy kane on gluten free English muffin burger was fabulous, except my lettuce wasn't very fresh. Fries were awesome. I loved all the sauce options, especially the special sauce and hatch chili mayo. Service was super friendly on the phone and when I came to pick up. The location is a tad hard to find -- they are located toward the back of another building. They are super covid safe. Takeout only as of end of March 2020. Pick up at a window, so you don't even enter the restaurant. read more

Absolutely fabulous burger. Cannot recommend it highly enough. Juicy with wonderful flavor and crispy fries that compliment everything. It's a little tough to find, there's no street front situation. It's on what would be like a public square with a small corner store. You have to really hunt for it, but do it. It's sooooooo worth it. The night we went we sat outside and a band was playing in the square and it was just the best!!!!! Highly recommend and we'll be making the drive from Phoenix again definitely read more

Diablo Burgers basically delivers tasty burgers in the form of English muffins in downtown Flagstaff. With our trip in Arizona coming to a close, reviews and blogs all mentioned that Diablo Burger was one of the foodie spots to check out in Flagstaff. Because its prime location at Old Town Shops, parking can be quite hard, but the restaurant itself is hard to miss. Joe Sorren's mural "The Veridic Gardens of Effie Leroux" a surreal dark painting with whimsical flare plastered along the cylindrical wall that encompasses the restaurant. In terms of the food, I thought was solid. Their niche is that all their burgers use English muffins instead of a traditional bun. It definitely provides a different experience because of that crunch you get from the outside and the chewy center that soaks up the flavors on the inside. I had the Wrigley Field which came with sharp cheddar, grilled onions, bacon, and spicy sauce. However, the downside of using the English muffin is that it is definitely on the smaller side. The order comes with a side of fries which came with a unique blend of seasonings that definitely takes it a notch above your typical burger joint. While I loved the flavor, the fries were a little bit on the soggy side. I also thought they provided WAY too much fries to burger ratio which seems weird to dislike. However, when they were not super crisp and heavily seasoned as it was, hard to finish with the burger. Service during COVID is only to-go orders only. You may call or order online in advance. Dining tables have been blocked off, but if you are lucky, there are several public dining tables in front. Would love to go back when things are open again! Overall, Diablo Burger provides an interesting spin on a burger that is on the pricey side, but worth checking out if you are in the downtown Flagstaff area. read more

My aunt and I both have celiac and a dairy allergy. We shared a burger on a gluten free bun with fries. The staff is FANTASTIC! Very knowledgeable, extremely helpful, all while being extraordinarily friendly. Often it feels like our food issues are an imposition when we eat out, but not here! The gluten free bun is also dairy free. It does look more like an English muffin than a bun, but in my opinion that's great because there is absolutely no mistaking their regular bun for their gluten free bun, and it tasted great too. It was recommended that we have the burger cooked medium rare, so we tried it that way. For both of us it was a little less cooked than we would ordinarily choose, and I think next time we will go with medium well just because of our own weirdness about the way we prefer our ground beef cooked. That said, even still, the burger was excellent and the fries were fantastic! Often we go to places with safe options for our dietary issues, and it's clear that our husbands would not feel like the food was hearty enough. This place has thick hearty burgers that would satisfy the biggest carnivore. We will definitely be back, next time with our gluten and dairy consuming husbands! Thank you, Diablo Burger for a great experience in every way! read more

The food was very good. Loved the English muffin for a bun, and the huge portion of fries. Wasn't a fan of the small seating area both inside and outside. Also the parking was not ideal. Would recommend however if you were in the area. read more

Diablo Burger - The Cheech Burger - Burgers Near Me - Flagstaff, Arizona

Well my husband has learned a valuable lesson to look further down in the reviews and look at pictures. Where do I start......whoever at this joint thought English muffins was a good choice for a hamburger bun is sadly mistaken. We should have seen the red flags the moment we walked in and before we paid. First things the wobbly tractor chairs inside were horrible and forced us outside with the flies. When we ordered my husband ordered the BIG daddy Kane and I ordered the Wrigley Field. Now..... both of these items represent large things right???? Well they were not in any way. The concept of the burgers is good but to put a small hockey puck meatball shaped piece of meat on a English muffin is just ludicrous. The burger had no flavor. When I ordered the girl asked me if medium rare was ok and I said yes... well the cook obviously didn't get the same memo. Our tomatoes were bigger than our burger and there was only 1 piece of bacon as well. The fries or frites ( bad attempt at being bougee) was over priced for a basket and whoever thought of putting herbs de Provence on the fries needs to go back to cooking school. Also serving bits and pieces of potatoes smaller than 1/2 inch is not good business. Now I understand you don't offer fountain drinks but 3.50 for a bottle of tea and when you offer water at-least bring it out cold with ice. Not worth $52 and 6.00 to park to walk there. If you value your money find somewhere else to eat if your looking for burgers that cost less than $16.75 each. read more

Pros: this was a massive burger. You will not go hungry I went here on a recommendation from a friend who had gone to college here, and unfortunately I was a little underwhelmed. I got there right when they opened and had the place to myself. The women and the counter were very nice and the service was excellent. I had the one that comes with cheese and bacon and sauce (1000 island) and ordered it to their recommended done level of medium rare. It was served on a gigantic mound of fries, which had a pretty good flavor. The burger however was really dry. The flavor was good, and I liked all the toppings, it just could have used more sauce to balance out the dryness of the burger. read more
