The only place I HAVE to visit when I’m in Cali! I ordered the XXL burger because I was starving but I barely made a dent in it. This is not your average burger joint, the burgers have a good char on the outside and seasoned well. I would give 5 stars if they had a better bun, the bun is basically white bread, a brioche bun would knock any competition out.

I ordered the 1000 Island burger and son ordered the chicken sandwich and the skinny fries (gross). Husband ordered the L burger, we would not go back the restaurant was dirty, ketchup was watery and it was very overpriced!

Went here on a recommendation from Daym Drops. I hadn’t had a Fat Burger in over 8 years. It was good tasty. I could have used a less dry bun and the meat I think was pressed too much. It made it a little too dry. Next time I will try to order the temperature. Great visit tho.

I will not be going back. Tasted like a over salted steak and shake burger that’s been reheated. Wasn’t a flavor in anything else.

Honestly the best burger chain out there. The meat is no joke so good being so flavorful crisped up as a smash burger. Combine that with all the works topping and you have a perfect burger. Or you can try out their new burger, the Hang-in-there burger which is the same burger but with all the toppings to break new years diet goals lol. Live a little and live well eat Fatburger. Oh yeah dont forget the off the menu item sweet potato chili American cheese fries with a fried runny egg to top you’ll thank me later lol
