Reviews
"Was soooo excited to finally try this place. Everything is made (fried) fresh. I ordered the Fat Cow and was disappointed it didn't have the mac and cheese it claims it has. Other than that, my husband loved his chance, and the kids loved the fried oreos. We will prob be back, and I hope they don't skimp on the mac."
"One of the very few late night dining options available that’s both inventive, generous on portions, &?outside of the traditional McD’s Wendy, & the King, along with (of course) Taco Bell, I decided to try to make a quick run there to pick of something outside of the box, & filling, at around 11:45pm, only to find out that they were not taking any more orders tonight, because they had nearly been robbed just minutes before I arrived. It’s an absolute shame that crime has gotten to the point where most businesses won’t even stay open past 9 or 10 pm, but when it comes to your front door at one of your favorite spots, this has gotten out of hand. Better security measures must be put in place to patrol these businesses, so that they’re allowed to remain open, benefit the part of our community that perhaps works nights or different hours. This was a big disappointment & reality check, & I hope that the nice folks at Fat Shack are able to work with local authorities to ensure continued safety of both employees and patrons in the future. My stomach is straight up aching, & I guess I’ll have to settle for the nearest Taco Bell that’s probably out of fries."
"It’s nice to know there’s late night places like this to fill your pie hole with! There’s so many good sounding things on the menu I had a hard time deciding. Whatever you pick, I can’t imagine it wouldn’t taste delicious. Mine had chicken fingers, honey mustard, and fries on it. Man it was tasty. Also got a side of fries and they were crispy and delicious. Great spot for some late night food!"
"Big portions! Came here with some friends for dinner. Dinning area was small, so most people coming by had online orders. Service was good and so were prices for the amount of food you get. I got the fat slob and was not able to finish it cause it was nice and stuffed. Milkshakes were also good. Everything looks good on the menu. Will have to come back to try more items. Me and my friends agreed it was a good place to eat."
"This place is a crazy experience, I can see why this joint has a reputation for the late night muchers. The store itself is tiny, befitting for a goblin like myself (helps me get to places quicker). It's pretty dark with all the black paint, though. And the wait to get your food is pretty lengthy, but the wait is reasonable for the food you get. That food is a drunk's dream. Fries crammed into your choice and style of sub. And the sizes are thicker than the examples. So choose wisely."
