Small pop-up in a bar but plenty of space for people to enjoy the food. Asian-inspired smash burgers was something I never even considered but this was a great idea. Japanese, Korean, Filipino inspired flavors and they were delicious.Food came out relatively quick but they make everything to order so you are always getting hot food. Service was great, everyone was nice. Recommend if you want to try something new.

Looking for a hefty SMASH BURGER!? Check out Flats Burgers currently located inside Rock's Den Bar. They offer Asian-inspired flavors such as Sarap Manila (Filipinx), K-Pop (Korean), and Wasa-Bish (Japanese). They also offer a classic American Smash Burger.I really wanted to try all 3 of the Asian-inspired Smash Burgers, so guess what? I got all 3 because why not!? Sarap Manila is made with Longanisa and Banana Ketchup. How could I not get that!? K-Pop included Kimichi and Wasa-Bish had a Wasabi Mayo sauce. Each bite 100% lived up to its name and each one carried a uniqueness that you cannot find anywhere else but at Flats Burgers. The buns were buttery and soft, the patty was, of course, flat or smashed, but you get 2 patties and its just cooked to perfection where each bite of whatever burger you order, your tastebuds will be dancing. My personal favorite was actually the Wasa-Bish, because the Wasabi Mayo sauce they blend together was soooooo yummy!! I needed more of it so I ordered extra sauce on the side to add a little more to the buger.They also offer fries, tots, loaded tots and wings. We also ordered their loaded tots with longanisa and oooo that is a meal on its own! A generous amount of longanisa and sauce coating almost every tot. They are located inside a bar so expect people sitting at the bar or playing pool in the back table. It's honestly a chill place if want good food, some brew, maybe watch some game on one of their TVs, play pool or just hang out.Parking can be tough. Street parking so just be mindful and don't forget to pay!

If you're in SF, you need to check out Flats Burger inside Rocks Den (open Mon-Tues, 5-9 PM). They specialize in Asian fusion smash burgers, and they don't disappoint.The K-Pop Burger was my favorite--juicy patties with kimchi, creamy kimchi mayo, and kalbi sauce for the perfect smoky, sweet, and spicy combo. The Filipino-Inspired Burger with chicken and beef longganisa patties was packed with rich flavor, and the optional fried egg made it extra indulgent. The Wasa-bush Burger had a great wasabi mayo kick, though I think a pickled cucumber would've balanced it even more.Their sauces--like K-Pop (kimchi mayo), Wasabish (wasabi mayo), and Sarap Manila (banana ketchup mayo)--are all house-made and amazing. Pair your burger with fries, Cajun fries, or tater tots for a perfect meal.The staff is super friendly, and you can taste the care they put into everything. Flats Burger is a hidden gem--definitely worth the trip!

Fantastic new Asian inspired burger spot in San Francisco. They're located out of rocks den in the excelsior on Mondays and Tuesdays. Their burgers are unique for sure, but if you're willing to try something new and different I would definitely recommend. The service was on point, a couple of good kids running it. Prices were decent and the overall vibe of the bar was chill. Nothing crazy, good place to get a beer or cocktail and a burger, maybe catch a game. Hit em up!

After trying 3 out of the 4, (Wasabi, K-Pop, Manila)I'd rank em in order,1. Wasabi2. K-Pop3. Manila1. The wasabi burger has a nice unique sauce that gives a slight kick of a wasabi burn through your nostrils, but nothing too overpowering. 10/102. The K-pop burger also has an interesting taste, kind of similar to spicy mayo, with a kick of kimchi. 9.5/103. The Manila burger is a very interesting and unique concept. I wasn't the biggest fan, but I'd say some who prefer sweet over savory would definitely enjoy this burger. I'd recommend adding an egg! 8.5/10Overall, the food is dope and some of the best smash burgers in SF

I'm sorry but no. The Wasa-bish burger was mid and the patty was bland and not seasoned. The tots tasted burned idk if they were overcooked or deep fried in old oil but it had a burnt after taste. Not sure if I came on an off day but for a $12 burger this was very disappointing.

We ordered 2 burgers, loaded tots, and 6 pcs chicken wings. We waited 30 minutes and by the time we got our food, our beers were getting warm. The burgers were good but the buns were cold like they just took them out of the fridge. The tots were crispy on the outside but on the inside, it was almost wet from how greasy they were. Wings were good but based on how small they were, I felt like $10 for 6 was overpriced. I liked that they have two pool tables.

First timer here at flats and it did not disappoint. The burgers tasted well seasoned each with their own unique flare. The Sarap Manila was the most unique and a must try! However, the others were also very good as well. The fries were perfectly crispy, the Cajun fries stole the show over the seasoned fries. We tried the Lemon Pepper and the Buffalo wings, both were good but the crisp on the lemon pepper was perfection. The workers were very attentive and friendly which was great as well. Definitely will be back and will be telling everyone I know to try it!

Flat Burger is located in a bar in the mission district. I had forgotten the burger names, but my girlfriend and I had gotten a philipino, korean and japanese inspired smash burger. The food overall was good and two of my favorites were the philipino and korean burger. The philipino burger had longsnjsa and egg. The korean burger has hints of kimchi which helped cut the fattyness of the burger. Usually when I eat smash burgers I get so satiated and overwhelmed by the grease. These burgers however with the addition of their vegtables helped balance it out. I would come back again if I were in the area. 5/5
