Not a good option if you’re looking to eat healthy but a great option if you’re just craving some deep-fried food! I got the chicken and fries, mozzarella sticks, and onion rings. I tried my friend’s classic burger and it was the best dish out of all the ones we had so definitely recommend! The staff is friendly, there is a big variety of fountain drinks and teas, and overall the laid-back atmosphere of a casual fast food joint is achieved.

The foods pretty much what you’d expect. I got the fat shack and it was freaking massive. There was so much in there, but it was still somewhat bland. Might be good for some late night snacks but I wouldn’t go there for dinner again.

Adjusting from 1 to 5 star. Delivery driver wait time has been considerably better and I haven’t had a major issue picking up from here in weeks. Great job guys! Delicious food here – can never go wrong with the classic single or some mac and cheese bites.

Fat shack is for sure a good munch to grab while on the hill. I believe their fat cow as well as wings and fried Oreos are out of this world. They sadly don’t have fried pickles anymore so that’s a bummer but it’s a good community of workers that support our tummies.

Elvis cooked some life changing food. And dan made a top tier shake. Chillest dudes out there and they got great service with great food. All around 10/10

Ordered a fat doobie and it didn’t have all the ingredients. They loaded it full of fries and skimped on the other items. When I brought it up they made me feel as if I was lying about it. Finally offered to make it again but it was too late.

I got the vanilla milkshake, it was kind of bad. Added way too much malt powder to the point it was overpowering. But that might come down to personal preference I guess. probably mostly because I ordered delivery but it was also mostly melted and did not have a milkshake like consistency.

I had the Fat Slob and it was amazing. I’ve never had a sandwich quite like this before and I must say not only was it delicious but it was unique. The food was a little pricey for what it is but it’s late night frat food so I can’t be mad. Bonus for being open for the night life.

Omar, Dan, and Elvis the best workers at this whole place. Food is fire and the service is super good. Best restaurant in Boulder

Food is good enough but thanks to delivery by DoorDash I can never order, would recommend just going out at this point because delivery is not a thing
