We really wanted to like this place but their food just didn't meet our expectations. We went on a Friday night around 7:30pm right before a huge crowd came in right after us so we thought that was a good sign. The employee that took our order was friendly and patient as we decided what to order. My husband got the Fat Shack sandwich and it was mostly French fries, with one mozzarella stick, some cheesesteak, one big chicken tender and no jalapeño poppers or onion rings. It was also drenched in their honey mustard sauce and he said that all he could taste was mustard. He ended up throwing most of it away. I ordered the single patty burger with bacon which was ok. Could have probably used a little more of their sauce but it didn't look anything like the picture on their menu. The only thing we really liked were their onion rings. We pass this place all the time and we're hoping it would be a new favorite but we won't be going back. read more

I absolutely love Fat Shack and everything about it. I got my first sandwich from the location on University but this one is close to my house (though sadly they don't deliver to me and it breaks my heart but my waist line is grateful) so this is where I go. I can't even fathom getting a sandwich at another shop. I have never had a bad sandwich here. My favorite is a fat doobie. I don't care if you think you hate honey mustard - you don't. Get it on the sandwich you will love it. They always let me add an extra piece of chicken to my sandwich for my daughter to eat. I've never made it all the way through the whole regular sandwich as there is so much on it. Chicken strips, Fries, Onion Rings, and Mozzarella Sticks. It's so good. You can only eat one every so often or you just might have a heart attack but the staff is so awesome. They are even known to sing along - loudly- to the radio. I met the owner once when I was there and he's simply the best. Check this place out if you want the best sandwich every! Also three words - Deep Fried Oreo's read more

Hands down the best place an staff are so polite an helpful for first timers Quick an friendly staff satisfy your taste buds with fat shack it's the way to go read more

Great food; happy for my cousin and the success they've experienced with this out-of-the-box menu.

I love this place. Prefect for when the late night munchies hit you.. cant go wrong with a fat doobie, bugers are amazimg as well

They're always consistent and have a wide delivery area. On Sundays you can get discounted wings and chicken fingers. The food takes a while to come out but that's only because there are a lot of potheads that work there (as you can imagine). read more

Wanted to try it because of the appeal. It's like anything and everything fried all mashed into a sandwich. Had it for dinner because we were curious. Totally not for me!!!! read more

I was happy to finally try this place. There is nowhere like it. It definitely is for select tastes, but it's pretty obvious from the menu if it's for you or not. I got the 'Fat Shack' sandwich just to go all out. I think something with less on it may have fit my tastes better, but don't regret the choice. Next time I'll probably get something where I can taste the individual ingredients a bit more. read more

I won't lie, my sandwich was extremely tasty! Wouldn't change a thing. Service was fine too, no complaints. ...Just way, way over priced for what you get. So many options available as the Denver metro grows. I can't imagine this franchise will go too far or expand in any way. Now, all that said, if I was drinking heavily and needed comfort food within range of their delivery zone, I would happily call them for a late night sandwich. read more

I order from here on a bi weekly basis and the food is bomb AF. The milkshakes and wings are always so good and the delivery time is reasonable. read more

So I've known about this place for a while but was always too lazy to drive there. Well today I'm 10 weeks pregnant so I couldn't think of a place more fitting to hit all my cravings at once. I got the fat cow (which is how I feel after eating the whole thing) it's so good. This is the first food that I've eaten since becoming pregnant that I didn't hate half way through. Good job! read more

Pretty darn good. I ordered the wings. I expected little B-Dub size wings so I way over-ordered because they were more the size of chicken strips. Good value though, and very good. Staff was very friendly and accommodating when I went to pick up my order. read more

Healthy...no. Delicious as hell...absolutely. First of all, people complaining about calories??? Really??? Who'd of thunk 'The Fat Shack' didn't abide by your boring standards of kale and misery. I digress. I have been eyeballing this place for a while now and peeked at their menu a few times so today I stopped by to give them a try. I can only say that it was delicious and I will be returning to try more off of their unique menu. If you just want to indulge in some delicious food stop by and try some of the Fat Shacks crazy concoctions. read more

This was the best sandwich I've had in my entire life. I got the Fat Bronco--chicken fingers, cheese sticks, french fries, and marinara. The marinara is perfect, as is the chicken. We also got some fried Oreos and a fried Twinkie. I've never had either of these, so I don't have a comparison, but this is by far the best dessert I've had. The chocolate in the Oreo was like cake, and the cream in the Twinkie was melted heaven. We will definitely be back, not too often, though; my waistline couldn't take it. read more

This is what happens when a stoner with a culinary mind gets their hands on a business license and a deep frier. If this sandwich leads to heart failure and my untimely death, it will be worth it. Cheesesteak, cheese sticks, jalapeno poppers, French fries, and onion rings in one sandwich... that's mad... deliciously insanely mad. read more

Delivery time was spot on what they said or I'd give only 1 star, we ordered the fat chance and it prolly would be good if you where drunk with the munchies , we also ordered the onion rings that where soggy and greasy , the wings where just weird is all I can think to say , soggy and fatty. The total for all that was 28$ plus tip, we won't order again as we threw most of our order out. read more

This place is So SO SO GOOD. Customer service is amazing ! Alex was such an amazing employee! After hours of being stuck in a school it was great to come here and get such great quality service. Mozzerella sticks were almost the most amazing thing ever !!!! read more

Food was soggy and cold, only redeeming quality was the fried pickles albeit over done. If you going to allow delivery of you food how about send it un assembled st there is a chance at crispness read more

This place is exactly what you would expect from looking at the menu. Funky creations to please the late night crowd. The house specialties are their fat sandwiches, and the title doesn't lie..these sandwiches will make you fat! However, this is the point to this place. Their motto is, "Late night done right." Catering to the late night crowd is a task not many delivery restaurants do, but, at the same time not many restaurants offer sandwiches with Philly cheesesteak, onion rings, jalapeño poppers, fries, and honey mustard. Their dessert menu offers deep fried treats covered with powdered sugar, or if you don't see something that will satisfy a craving, they will deep fry anything you bring in for $1! The fried rice Krispy treats were obnoxiously rich and delicious! The delivery we ordered was a little slow, but I expected that from a place that has been open for less than a month. This place will fit right in, in Colorado! I wish I had thought of an idea like this first! You can bet I will order from here again, especially since they deliver till 3:00 am on the weekends. What better way to end a night filed with libations than a junk food fueled after-party? read more

We ordered take out from this place and were not impressed. There was really nothing special about any of the food except for the excess in calories in every item on the menu. read more

I would say this is good food if you're drunk-- it's hard to find anything without chicken and when they delivered they forgot my sandwich and when they brought it to me it was cold. read more

Food was 'bar food'. It was not horrible I MAY try another location. Can't expect too much too late though I would expect the same respect. My fiancée and I went with some friends of ours. They got they're food though missing 3/6 deep fried Oreos. The people that order directly after us were eating before we got our food. Order was wrong. I was missing my 'toppings' although stated just no onions. I ordered a shake. I had to ask for my shake and the bag for my leftovers. somehow my this happened to the only colored people here. Ashley was management was on duty. She barely recognized us standing there and then stated she didn't have a drawer in the register to help us. read more

Ordered two Phillys at midnight. Sandwiches were delivered promptly in 25 minutes. The meat to bread ratio on the Phillys was outstanding. They were delicious. Would order here again. The fact that they stay open so late is amazing. read more

First time ordering and I am not disappointed. Food was good, especially the Mac and cheese bites, buffalo ranch was a nice surprise, and it came in under the 30 minutes that they stated. And the lady on the phone was very nice. Will totally order from them again, no doubt. read more

My favorite place to eat whenever i am in town! I wish we had a location in chicago. But anytime i am in thornton fatshack is a must at least twice!! read more

Mmm... deep fried Oreos. Good food, good music, good service, funny shirts, open late. Appreciate the thick slice of tomato on my burger. Thanks Fat Shack! read more

Not too shabby for some late night eats when you have fat girl tendencies! Lol I was sold on the deep fried oreos!!!

The Fat Shack in Thornton - WOW! This was our first visit and we loved it! The wings were crisply, sandwiches were filled, and the burger was very fresh! Not only that, the dessert was absolutely to die for (deep-fried cheesecake). Overall, I would recommend this place any day! It has something for everybody. read more

Oh, man, I am way too addicted to this place. I always get the Fat Cow and I can never get tired of it. Macaroni and cheese with chicken fingers and onion rings, I never imagined this combo to turn out as good as it does. To top it off, I like to get the deep fried funnel cake. Heaven! Plus, the deliver with uber eats so I never have to make the drive! 5 stars! read more

Wife and kids wanted burgers and I wanted something besides your traditional fast food burger. So I figured I would give this place a shot and stopped in for takeout. It was about 6:30pm on Saturday and the place was completely empty. All four employees seemed to be standing there waiting for something to do. I ordered two double burgers, one single burger and a kids chicken fingers meal. I figure, place is empty, I should be in and out no problem. I grabbed a seat in their dining area and waited and waited and waited. As I waited I could here phone orders being taken so I know my order was not the only order they were preparing but my order was the first order. About twenty minutes into the wait I heard one of them say that they could not find a ticket but I did not think anything of it. Almost forgot to mention, one of the kids in the back is a very talented and loud belcher as he displayed his skills at least three or four times well I was there. About 10 minutes later " The Belcher" came out and said that my order was done but my ticket was the one they had lost and they did not know what was on my order. No big deal, I told him what my order was and he brought my food out. When I got to my car I checked the order and the food was already cold. Probably because it sat in their kitchen well they tried to figure out what I ordered. The food looked delicious but eating it cold just ruined it. Well I was waiting 30 minutes for my food I did happen to read an article they have on the wall about the founder and a co-owner of The Fat Shack. Pretty inspring article. I guess both were 27 yrs old when the article was published. I know they have more then this location and they can't oversee all locations all the time. It's just a shame that you can work so hard to accomplish so much at a young age and you have employees that are there just to collect a paycheck and couldn't care less about something you put your blood, sweat and tears into. read more

Super dank sandwiches. Was impressed. Not your ordinary sandwich shop but it was super delicious. Try it if you haven't you won't be disappointed. read more

This is a interesting place. All the food is explained in the title. I will return to this place...

The food is decent. I've ordered delivery as well as in-store a few times. My gripe has to do with my most recent delivery. Their website prompts you to tip before actually receiving the order. I tipped generously. It took an hour and 20 minutes to arrive, which was 25 minutes after the promised time. When the driver arrived, she asked if I paid online. I suppose I could have ordered and not paid. I didn't receive a receipt. She offered no apology or reason for being so late. The food was cold. I don't recommend ordering from this store. read more

Pretty cool lil place. Great food and you get a lot for the price. If your on a diet this is not the place to go!!

Would be a 5 star, but loses stars because of their very limited delivery area. Need to expand it!

My first time having their fat shack sandwich and man did it not disappoint. So many favors along with so many sauces to choose from. The honey jalapeño mustard was great. The 8 inch sandwich was plenty of food. I even had leftovers for lunch the next day. Noticed that they also had milkshakes and I chose the Reese's specialty shake. Will for sure be making more trips to this place. read more

I love this place. Exotic sandwiches and Brad and the crew are always friendly and make good sandwiches!! Please keep this awesome crew as they really make this place my every Wed night tradition after work ! Thanks again !! JFK read more

Food taste good but SERIOUSLY over priced! Don't think I'll be back. This stuff is not good for you anyway. My son got seriously ill after eating some crazy Mac n cheese sandwich with all kinds of stuff in it. He didn't like it. read more

fat shack is the place to go man!! they have such cool sandwich combos! don't know where to go out to eat? go get some fat shack you won't be disappointed!! The staff here is sooo chill, alex is such a sweetheart WE LOVE ALEXXXXX!!!! read more

I would give 5 but as previous reviews have stated delivery area is way to small. The Fat Shack sandwich is all that and more but please expand delivery area. Late night food is hard to come by in north Denver so this place fills a void but doesn't deliver to most of it. read more
