The burger was well-cooked, although a little salty. The bunnwas soft but a little chewy. Probably would be better if it were toasted. The fat fries are my favorite part of the meal. The restaurant was clean and the employees were polite and helpful. The parking at this location is insufficient. On more than one occasion I have driven by due to no space. Overall, there is no good reason to stop here. Just down the street is an In-N-Out. Better burgers and better fries

Hands down one of the if not the best burger in Fontana. I had the XXL burger with bacon and cheese. It wasn’t soggy and it tasted fresh. It was a little on the pricey side….. but totally worth it. The staff was awesome when I went the guy that put the burger together was really nice . Wish I got his name.

I’ve always wanted to try Fatburger but I always assumed it was only in LA but was in the area and decided to try my local chain. The store isn’t always busy so orders are quick and clean. They have an impressive menu with multiple add-ons. They include milk-shakes, wings, and hot dogs for signature sides. The smash burgers are very good and juicy with the right texture. Not to mention the music choice is the best.

Burgers are good gives me In-N-Out vibes hands down oreo milkshake is bomb… Bone in wings are very good we tried the cajun and lemon pepper and boneless coconut jerk… onion rings could be cooked little bit more… chili cheese fries we’re good to maybe next time we’ll get the string fries instead.. pretty pricey they charge you for cheese and Extras.. but if you’re looking for a home cooked hamburger like fast-food way this is your place.

First Time Trying Fatburger and it was pretty good got the XXXL Burger. ( it was Huge ) with onion rings and a large Mr pibb great tasting burger. Super juicy and cooked to perfection. Only issue is that it’s pretty pricey $27Bucks for a combo. Ridiculous also I think my burger had relish on it and I’m not a fan of relish so I wish I would have known so I could have asked and not had it on there. Will be back But I think I’ll get the XL burger next time. Also it has a really small parking lot. About 7 or 8 spots only and the Starbucks drive-thru line is backed up behind the parking spots so it’s really difficult to get in and out

I request light Mayo, the cook was using utensils and turn to prep our food. When I said light Mayo he actually took his fingers and wiped the excess off….Messed our shake . Remade it and took it to the back, pulled the one with the whipped cream out the freezer went out of view to do what to the Shake…..who’s knows
