FireFly Burger - Backfire double, and Wisconsin cheese - Burgers Near Me - Garden Grove, California

I have wanted to try this spot for a while, I was excited to see a spicy choice so I went for it! The backfire is loaded with chili lava sauce jalapeño lettuce tomato cheese and onions. The bun was not fresh and the burger it self fell apart as I was eating I thought they used too much chili lava sauce. The patty did not have a lot of flavor, although it was not over spicy is ok the over all burger was not satisfying. read more

Food and services were amazing!!!!! You must try it! The guys were really friendly. Burger were delicious! read more

Came here for the first time today for lunch since I was in the mood for a cheeseburger and this place came up on my Yelp search. Once I arrived, I noticed it had a restaurant type ambiance with lots of seating and decor on the walls. I was expecting more of a casual burger spot like In-N-Out or Five Guys for some reason so that caught me off guard. I ordered a double smash burger with fries and a drink from the touch screen kiosk since it appeared that there was only one young guy working at the time and he happened to be in the back. He came out after I paid for the order and asked me what I ordered since apparently their kiosk system is broken and wasn't sending the order to the kitchen. Not his fault but that's definitely something they should get fixed ASAP... although I didn't mind, some people may get annoyed having to repeat their order details. There are also many price discrepancies among the items from what's displayed in the touch screen kiosk vs the hard copy menus that they have sitting on the counter, another cause for confusion. I highly suggest getting rid of the hard copy menus and cleaning up your kiosk menu interface and process and using that exclusively and displaying the menu on TVs since those prices can be easily updated. Anywho, after about 10 minutes, my order finally came out. The burger looked pretty solid. I was expecting grilled onions since onions are typically sliced thin and grilled with the patty for a typical smash burger recipe but it came raw. But nonetheless, the burger was still delicious. The fries were good too, although I would have liked it a bit crispier but that's neither here nor there. So in terms of the menu price discrepancies and the ordering process, there is a lot to improve on. The young worker was friendly and accommodating which made up for that. As far as the food itself, it's solid. Grilled onions would take their burgers to the next level though. read more

I visited Firefly Burgers in Garden Grove on June 18, 2025, at around 11:05 AM, just after they opened. I was the only customer, but the older man working (possibly the owner) was rude from the start, no greeting, just told me to order at the kiosk with an attitude and no help. After ordering, I waited over 35 minutes total without any updates. I stepped inside midway to use the restroom, which was absolutely filthy. The front seating area looked okay, but the open kitchen was clearly dirty and messy. I ordered a smash burger with cheese and added mustard, a Caesar salad, and mac & cheese bites. The burger was disgusting--cold, missing the basic toppings, and had so much mustard it was drenched like he dumped a whole jar on it. The salad had no croutons and came with random mushrooms, which weren't even listed. Everything tasted awful. I spent $25.55 on food that went straight into the trash. Rude service, long wait, gross bathroom, dirty kitchen, and nasty food. Never again. SAVE YOUR STOMACH . Look at the pics. I'm still in disbelief. read more

Happy National burger day...... and of course after a small hike we had to stop here..... thanks Yelp for the recommendation. Came in for lunch, the place was pretty empty yay for us:) the whole vibe inside was great... totally different from the norm. Service was excellent as new customers we received 20 percent Off . Our food was soooo good I was pleasantly surprised highly recommended just keep in mind that the parking might be tight since they share parking with other vendors and he can get busy due to Starbucks next-door. read more

This place was an anomaly. It has very good reviews and the pics look amazing online. When we arrived parking was very tight spaces. Walking in its order at the front and we were meet with stares. The only reason I chose this spot was the first review pic had wings that looked amazing. I get there and the menu has wings in the picture but not in writing. Ask if they have wings and she says no! Ok then wife got the burger with egg and I got the chicken tenders. Got meals but wasn't asked what we wanted to drink. Sat down and the vibe is just strange. Finally go up and ask if we get drinks and she says yes. Food takes a minute but when it comes it looks better than I thought it would. Wife's burger is tasty and fries are decent enough. My chicken tenders were not bad but not great. The beading was something you'd expect on an onion ring and maybe over fried as they were very dark. Tasted ok but not great. 2.5 stars would be my rating. Not the worst but not the best. read more

So good. Love trying new halal burger spots. The spicy jalapeño burger was amazing. My favorite side was the fries. They're so crispy and soft inside. Best combo. They have a lot of sauces too so if you're into sauces this is the place for you! There is parking nearby in other lots in case they are busy and the lot fills. read more

Oooof, was so excited to bring friends here after loving my first experience here but walked out completely disappointed today. How do you have just 1 person at the front on a Saturday? There were five big parties inside and ONE guy running from the register, to the back, bringing the food out, then running back to the kitchen, etc. I had asked him for the smoke gun and cheese injector & he said he would bring it twice, but he never did. I finally gave up and my burger was just cold at that point. If you're too busy, I'd rather you just say you can't do it today instead of making me wait. Also the fries weren't crispy or good (probably because the kitchen was trying to push out their orders quickly). Soda tasted like it had been opened in the morning; no fizz. I hope this restaurant can do better because there was so much potential before. read more

Beware of your receipt at this place they overcharge here. The combo says 10.99 and they charge 1399 on the receipt brought this to their attention and they credited me two dollars which still wasn't enough it's happened more than once I will not be returning bad customer service read more

Ate here for the 1st time last week. I just wanted a good solid burger, and FireFly Burger California met that expectation and then some. The patty was juicy, perfectly cooked, and had that real grilled flavor you hope for but don't always get. The toppings were fresh, the bun held everything together without falling apart, and the fries were hot and crispy. Nothing fancy or overcomplicated -- just done right. Service was friendly and quick, and the place had a clean, relaxed vibe. If you're craving a straightforward, satisfying burger without the gimmicks, this spot delivers. I'll definitely be back. read more

Every burger lover needs to check this place off their list! Came here with my girl, Kara around 12 for some Lunch. They do have a private parking lot, but it is kind of tight. (Shared with other places) We walked in and sat where we wanted. They have tables but they also have a few very large booths After deciding what we wanted we went back up to the counter to order. The men working here we so incredibly nice. He carried our fountain drinks to our table for us. Our food came out shortly. I can't remember on what burgers we got. But what I loved is all the side items. I'm a huge side girly and love dipping sauce. And they get a solid 10 in this area. We ordered curly fries Mozzarella sticks Onion rings and Jalapeño cheese poppers (With tons of different dipping sauce) For our burgers they came out and put on a whole show for us lol. They smoke your burger and then inject it with cheese. It was awesome! Again, loved the sides, the service was amazing and loved the burgers and how they smoke them and inject with cheese sauce. They actually put disposable gloves on each table for you to wear if you don't want to get down and dirty They are also halal, which is a plus We finished with two strawberry shakes which were amazing. They even pay attention to detail and put sprinkles on them. I love this! I will definitely have to come back with other friends and family. 5 stars for service - again, the men working Here were amazing. Great customer service 5 stars for food - I loved the variety. They also have smash burgers. I need to try them next. Hope you come try it soon and love it as much as we did read more

Firefly Burger isn't just a meal--it's an experience! They smoke your burger right in front of you and offer free cheese injections (yes, they pump melted cheese straight into your burger!). It's super fun to watch and makes the whole thing feel unique. The burgers are fresh and juicy , with both beef and chicken options. Their crispy fries and wide variety of sauces are a nice bonus! If you're in Garden Grove and want a flavorful burger with a fun twist, definitely check them out! read more

I went with the OG Firefly Burger. It's a pretty filling burger and you can choose to smoke your burger or you can just inject the whole burger with cheese. You get to watch this process too! The staff are friendly and the food came out in a timely manner. The restaurant has a cabin-like/sports feel and there's a decent amount of seating. I'd come back here to try some other burgers.

I decided to try this place after hearing how good their burgers are. However, the experience was incredibly disappointing. I waited 45 minutes to order and another 90 minutes for my food. While I understand being busy, the staff lost my ticket and began serving multiple people who ordered well after me. Despite me checking in repeatedly and explaining that I was holding a hungry one-year-old, and a 6 yr old pulling on my leg, I was pushed aside while they continued taking new orders. It eventually was revealed that my food was never even started. When I eventually got my meal, the bacon on one burger was rock-hard and inedible. I threw it out. Though the staff apologized and offered drink/fry coupons (with purchase) at the end, the experience was so frustrating that it ruined the meal. To confirm, this was not a food truck? It was the actually business! read more

Great burgers because you can taste the grilled goodness. My husband had the Firefly sandwich and I had the Original beef meal. Onion rings were extra, but the batter was thin and crunchy. There were enough tables with seats and large banquetts. Nice low key background music. Friendly service personnel to help with ordering the meal. Parking is tight with the nearby Starbucks. We made a reservation, but it wasn't needed at 6:30pm on a Saturday. We'll be back! read more

Love this burger spot! Inside has very nice seating and the burger I ordered (smash burger double patty) tasted delicious. I wish it was a bit bigger because one wasn't enough to quench my satisfaction. Also I did I mention that it is HALAL too? It was my first time here so don't have much to review but based on first impressions alone, I enjoyed the place. Would definitely swing by again in the future if I'm in the area. read more

I got the single smash with a side of fries. It's okay. Passable. They need a different bun for the smash burgers. The ratio of bun to meat was too sad. The fries were also pretty mid. Just tastes like frozen fries you can get from the grocery store. They really need to watch Kenji's burger video from NYT Cooking to see how they can improve. read more

The Best Burger I've Had in a Long Time! Firefly is the spot. The moment my burger arrived, I knew it was going to be good but WOW. The bun was insanely fluffy, soft, and flavorful, the kind you can only get when it's truly fresh. And the meat? Thick, juicy, and real you can taste the quality in every single bite. It's the perfect balance of hearty and healthy. Nothing greasy, nothing artificial just wholesome, delicious ingredients that come together like magic. I walked out already craving my next one. If you want a burger that hits all the marks fresh, juicy, healthy, and unforgettable Firefly has you covered. read more

8/10 Overall: I loved the ambiance of the place, it has a very homey vibe! They offer free cheese injections and have a smoked gun which was very cool. The food is delicious and the servers are friendly. They take their business very seriously! Backfire single $12: 3.5/5 this has jalapenos and hot sauce so only get it if you have a good spice tolerance! The meat was juicy and the bun was crispy. Bucharest crispy $12.5: 4/5 my favorite thing we got here but i wish the cheese was more melted. The chicken was crispy and i loved the sauces in this sandwich! Firefly Burger: $11.5: 3.5/5 your typical burger, it was delicious! It did get cold fast and the cheese wasn't very melted. Fires $3.5 & Onion rings $4: 3/5 I'm personally a fan of crispy fries, these were a bit larger. The onion rings were also pretty standard. read more

Great halal spot, especially during Ramadan since they're open until 4am. I came with my brother and it was a nice change from the usual late-night options.
