Solid burger. I just finished eating the undercover cheeseburger. I found it a little salty, but once I took the bacon out to eat alone (yummm) it was much better. I liked the heavy amount of pickle. One suggestion would be to cut the bun higher. The bottom bun is really thin and the top very thick. Seemed like a cool place, I will definitely give their $3 Margarita happy hour a chance some time. I also saw a $1 Marg sign for Saturday and Sundays. Pretty sweet. The guy at the register had to ask me 3 times, just the cheese burger? Yes... Yes... Yes... annoying. I'd return! B/B+ read more

Good food, bad service. Ordered through DoorDash. Checked in at the front and was told my order was being prepared. Ended up being for someone else and they hadn't started or somehow never received my order. Manager asked for my phone number and said he would text me a gift card for $10 to make up for the convenience, but he never did. Food was good. Manager totally blew it by saying my order was being prepared when it wasn't, then lying about sending a gift card. Love illegal burger but won't be coming to this location again. read more

I had the shredded pork burrito, smothered in pork green chili, and it was awesome. Fun environment.

Had to order for pickup only due to COVID-19. Food was amazing. Was disappointed when I got back to my room and discovered that they didn't put the illegal fries in my bag that I paid for. Didn't feel like walking back from the hotel. Otherwise would've been 5 stars. read more

Walked past beautiful Larimer Street and feeling hungry near Writer's Square, stopped in at Illegal Burger. Artistic, minimalist decore with black and white stainless steel pictures and metal chairs. Walls and ceilings are painted black, dimly lit with retro bulbs. Music was hard metal, which wasn't appealing. However the food was delicious. Friendly service, had the Boss burger - fresh pineapple sweet cooling contrast to the hot fried jalapeño stands out. A tasty cheeseburger with hickory bacon on a tender brioche bun. Would come back here for the food. Wished the ambiance was a little brighter and happier. read more

Oh. My. God. Don't walk: run to this burger joint! Beyond delicious- I had the Illegal cream cheese and it's perfection. I like a diner burger (greasy-spoon-slider style) and this hit the spot. Bun grilled and soft, perfect temp burger. We tried the 3 accomplices side, but the skinny Slammer fries are the best. read more

The guy who works at the front with glasses and the weird tattoos on his left arm was so amazing. (His name might be either Alec or Adam?) He was helpful and kind and made sure to show us the best items and how to order exactly what we wanted. The food was alright but the costumer service was what made me give 5 stars. read more

I wanted to love this place because of the menu selection, but it was underwhelming. We both ordered the Slinger and shared an order of truffle fries. My husband's burger was missing the onion fries which was strange since we ordered exactly the same thing and it was super obvious they were missing. Not wanting to cause a fuss he ate it anyway. The burger was good and very messy. My bun was soggy and fell apart which I hate. The fries were good, but a tad too salty and garlicky, but still the highlight of the meal. I was only in Denver for a short vacation, but this is not a place I'd try again. read more

On the edge of Larimer Square, a friend of mine and I pretty hungry from walking around Denver all day spot a burger spot and decide to walk in. As soon as you walk into Illegal Burger, the aroma of burgers cooking on the flat-top immediately hits... and it's great. Good service and better food. I ordered the Undercover Cheese burger (Cheddar Cheese, Bacon, Mustard and Pickle) adding fresh jalapeños and grilled peppers with a side of truffle fries. Phenomenal food. read more

Excellent burgers. Try the waffle-cut fries dipped in their house sauce. Full(-ish) bar on site so you can get a drink. Tip: save room for one of their hand crafted delicious **boozy shakes** afterwards read more

Visiting Denver for work and decided to order delivery. I ordered the condiments on the side and not on the burger. all condiments were on the burger and a lot of condiments at that. Very sloppy burger. With this being said it was good burger. I would have preferred to have my condiments on the side like requested and I would have like about 20 more napkins then they put in the bag. Delivery was quicker than the estimated time so that was a plus. read more

Easily the best burger I have ever had! Such great prices for the size of the burger. Went a little out of my comfort zone and order the burger with avocado and sprouts and so happy that I did. Florida really needs a few of these! read more

Love the cream cheese burger with a pretzel bun!! Have had amazing experiences the times I've gone!! Truly recommend! read more

Loved this place! Best burguer ever!!!! We also ate the truffle fries super yammy! I ate the BBQ burguer and was delicious and my boyfriend ate the jalapeño one also delicious. Service was very good, food was great. I will definitely go back again my next time in Denver. Totally recommended. I still think it was the best burguer i ever ate. read more

I've ordered delivery a few times and they are always quick and always good. Delivery drivers are not a-holes, and that's really something. (I order a lot of delivery from various downtown restaurants, because I can't ever seem to leave my desk. THANK YOU GUYS.) VEGETARIANS TAKE NOTE: I'm not much of a beef eater (every once in a while) so hear me out. Their fish sandwich, as well as their veggie burger, are out of this world good. You will not be disappointed. Their burgers are great, too. So are their fries and cheesy tots and and and. The sauces are flavorful. If you're looking for some hand crafted fried goodness, this IS the droid you are looking for. If you're a vegetarian (or 90% like me), you're not left out. I don't know about vegans. I can't help you. No one can. I'M KIDDING. This place is the bees knees. read more

Tried this place a couple months back when visiting Denver and I still can't stop thinking about it! It was one of the best burgers I have ever had. My significant other and I talk about this place constantly since trying it. They have unique burgers with lots of options. I wish I was closer because I would get it constantly! SO SO SO GOOD! read more

Delicious burgers! I meant to review when I left but I remember my order being very yummy. I wish I could have it again, maybe the next time I go to Colorado! read more

Man, this place blew me away. Unique menu, and mouthwatering combinations. The fries sealed the deal, coming in crunch ... clutch. Whichever. ;) read more

No complaints here. They're centrally located right in Writer's Square and it's counter service burgers and fries. I absolutely loved my burger. It was a good size and cooked to perfection. A little pricey, but that seems to be the standard anymore. Service was excellent. They came by and checked on us like 5 or 6 times, even though it was counter service. read more

My wife and I were shopping on Larimer Street and we stumbled upon this burger joint for lunch. Had never heard of it before. My first impression was that it was really warm inside for as hot out as it was. No biggie but it was warm in there. The menu had to be looked over for a little bit to figure out how it worked. They have many pre-made burgers. Nothing that I wanted to try. You get to choose your bun type, toppings, etc. I ordered a custom burger and some shoestring fries. Both were very similar to Smashburger's style of burger and fries. The burger was pretty good. Kinda got some greasy hands on the brioche bun but it was not too bad. My wife had a chicken club sandwich. She was not blown away but liked it. She would have liked more chicken choices as she is not a beef eater. We shared the fries. They were okay. Lots of small fries but you will get that. Would try it again maybe. Liked it but not blown away. read more

Was in town from out of state and decided to try this place based off of their Yelp reviews. They had a good selection of burgers to choose from, but unfortunately our order was the most undercooked burger I've seen. The patties were quite thin as well so not very hard to cook all the way through. Plus side, fries were good. read more

So overall, not terrible. However, we were the only people in there and it probably took 30 minutes for our food to come out. When we did get our food, the veggies on the burger were cut super thick, like unreasonably thick. It wasn't awful but I've definitely had better burgers and much quicker service elsewhere for either cheaper or the same price. The woman at the counter was very friendly though! read more

If you're in larimer square and looking for burgers, check out illegal burger! The environment is the most casual one you will find in this area. Ordered the off the record avocado burger featuring a beef patty, avocado, sprouts, pepper jack cheese, lettuce, tomato, and chipotle ranch sauce. Also had a side of their spicy onion scoops! Even though this is an order and sit down kind of eatery, there were workers who checked in on us frequently to see if we needed anything else. Only regret is not putting extra fresh jalepenos on the burger-- love me some spicy food! :) read more

Illegal is a fitting name. I ordered through doordash on December 27th at about 5pm. I paid almost 25$ for a burger , sweet potatoe fries and a milkshake. The burger was cold and raw, never recieved my sweet potato fries and the milkshake was freezer burnt and icy. read more

Illegal Burger - Writer Square - Very raw. I dont mind rare but that is undercooked - Burgers Near Me - Denver, Colorado

Vegan burger was clearly a frozen patty. Nothing special. It really bothers me when i order a vegan meal and it comes with non-vegan condiment (mayo fry sauce). If someone is vegan because they want to help the planet or prevent animal suffering, it completely defeats the purpose to bring (and then waste) an animal product to the table. read more

We came for a late lunch on a rainy Sunday afternoon. We were the only ones at the restaurant but the whole street and Larimer Square area was pretty quiet so we weren't too surprised. It looked like a great location - right in the middle of all the shops and other restaurants. We were able to find parking very easily - plenty of meters everywhere. We were greeted by a very friendly server who was very patient as we looked through the menu on the wall. I picked a simple, customized burger and he picked the special of the day. We...I mean I...had to add waffle fries. There is plenty of seating (high tops and low tables), as well as a bar and outdoor seating area. The food came very quickly and it was really well made and well flavored, especially the waffle fries. Also, they have chipotle mayo! read more

Amazing food!!! My husband and I just wanted something good to eat before we went to the nuggets game and I found this place on here!! Highly recommend, it is soooo good!! We will definitely be back! read more

We stopped in here after an Avalanche game to grab a quick bite, and found what we think is the best burgers in Denver. Thank you for the amazing food and service! read more

Sadly this gets 1 star. The food was cold. The burger was dry and over cooked. I asked for pink in my burger and it was just really over cooked as if they forgot and neglected it. Heard good things about the place so I was looking forward but left disappointed. read more

Read the reviews about long wait times for orders. Should've listened. After 30 min of waiting I asked and the order never went through. Got a refund and left ASAP since there are better choices around the area. read more

Good burger and fries, though no more spectacular than other local places. I would go here more often, but it usually has a line out the door at lunch hour. Lots of outdoor seating. read more

Great brioche bun ... get the truffle fries! Very casual setting - place your order at the counter and they bring it to you. With so many options and customizations, it's easy to get stuck behind indecisive buyers. The food is great though -- it'd get five stars if it had table service. read more

I am in Denver on a business trip. This burger place was close to the hotel. The yelp reviews were positive. After reviewing the menu decided to come. Wanted to order the hamburger with the hotdog on top but went instead with a cheeseburger. I added the onion straws. The french fries were delicious. read more

First I want to start by saying I was very disappointed in the service. Being from out of town I went to the internet looking for a happy hour spot I decided on illegal burger. Get there at 4 pm and on the outside it says HH specials along with HH burger. When I go in to order the girl I ask the girl behind the counter what is the happy hour burger and her response is IDK I think it's the sliders. She asks a guy sitting at a table on his phone and he says they aren't doing it anymore. I proceed to order because I read that the burgers were great. As I take my seat at which I see that the same HH special is on every table including the 1 where the guy was sitting. So at that point I was wondering was it just not available for me?? The waffle fries order was very skimpy but the Burger was top tier read more

Wow, delicious burgers made quickly! Definitely hit the spot. Also enjoyed a chocolate shake which was very tasty as well. I'd recommend looking at the menu before you go, since you order and pay right away rather than sitting and looking at a menu. read more

Took 30 minutes to get our food. There were patrons that came in after us enjoying their burgers. My daughters food was delivered after we had ours and then it was wrong. For $40 in burgers, 30 min wait and they still couldn't get it right. Asked for a manager, they apparently don't work on Sundays. read more

Wonderfully prepared burger! This is a new little burger joint my husband and I stumbled across before heading to the airport. The ordering was easy and we were offered some suggestion. My husband had the slinger and I had the off the record minus the sprouts. They were both delicious. They were larger burgers, so I think we could have shared but we didn't :P We did however share the combo fry set up with sweet potatoe, tater tots and truffle fries. The truffle fries and tots were my favorite. My husband enjoyed the sweet potato fries. (they are just never quite crunchy enough for me) This is definitely a place worth checking out. They have courteous service and quick made to order burgers. read more

Honestly, the beef was very bland tasting. Overdone with little flavor, it was surprising to me how bad it was for the price.

40 minute wait for two burgers. two groups behind us in line received theirs before us. sad.
