  1. Ok ok…I KNOW I'm a sucker for a good sandwich, but I also KNOW when I've had a great sandwich…and the other day Fat Stacks hit it out of the park!

    When we got the weekly Yelp email the other day, we (I went with Kevin G and Adam D) we decided to give this new joint a try.  When I saw the menu (similar to the fat sandwiches I used to get at the Rutgers grease trucks) I knew I was going for lunch…even if I had to go alone!

    So we took the short drive over and ordered three sandwiches- Kevin G made his own … turkey bacon mozz sticks fries ranch on the side.  Adam D and I split the Fat Stack (chicken tenders, chicken steak, Philly steak, Mozz stix, fries, and Fat Stack sauce) and the Viet Stack (Marinated Vietnamese Steak, pickled carrots and daikon, cucumber, cilantro, mayo, and Sriracha (like a Bahn mi).  

    I got upsold on the drink and cajun seasoned fries, but unless you are STARVING you DON'T need the extra fries. The fries were good (Cajun seasoned) but the sandwich fills you up plenty.

    Ok, so I personally LOVED both sandwiches, but the Viet Stack was my favorite other than needing just a touch more Sriracha, it was incredible. The combo of the pickled veggies and the marinated beef on the roll simply works!  The Fat Stack was also delicious but I felt like I lost the flavor and texture of the chicken and mozz sticks over the deliciousness of the beef and chicken steak meats.  My only negative with the sandwich was the fries that were ON the sandwich were a little under done for my liking, but I forgot to ask for them well done.

    After eating we also tried their shakes.  Kevin G ordered a Vanilla and Adam and I both got the mint cookies & cream.  I'm a big ice cream guy and this was really my only negative about my meal…the shake, for $4.75, wasn't nearly thick enough or flavorful enough.  I don't know if it was too much milk or just the type of ice cream, but the shakes were just average.

    Otherwise…place was spotless, we got a parking spot right out front (though parking here is likely to be very difficult as there is only on-street parking), the service was excellent, and I had two half sandwiches which will DEFINITELY bring me back to Fat Stack.

    I hope this place makes it!

  2. I'm at 3 stars for just a few reasons.

    1) The fries are clearly frozen. I probably wouldn't have as big of a problem with this if the fries weren't stuffed into my fat stack, or each of the 17 stacks on the menu for that matter. But because they were, they'd be better off with fresh fries like some of the other fresh ingredients in the other stacks (ie. My Viet stack had fresh carrots and cucumbers. If you just want fries as a side, it's $4.25 for a small and $5.50 for a large. Kind of pricey considering they're frozen.

    2) The shake didn't blow me away. It was kind of clumpy and icy. It probably has to do with the brand of ice cream they're using, but it almost tasted like the ice cream had freezer burn.

    Other than these two minor setbacks, the sandwiches are quite good, and all very reasonably priced at $7.49 each, but you are certain to leave hating yourself.

    They could could easily scale back the size of the menu to cut some of their food costs and start doing fresh fries.

    Overall, the staff is very friendly and even went as far as to ask for our feedback. Also, the place is immaculate, but it's only been open about 1 month as of this review so let's hope they keep up the cleanliness.

  3. So this is a pretty interesting concept and they deliver which is nice. Essentially your meal has sides built into a sub sandwich. They have standard creations as well as a build your own option (this is the route I would recommend as it's easy and you can get exactly what you like).

    The food quality is ok but it all kinda seems like it was in the frozen foods isle at a Costco. The chicken doesn't have the right texture and the mozzarella sticks are oddly spongy. I would pay an extra dollar or two for better ingredients for sure.

    The service people are nice but pretty difficult. I've ordered a couple times via phone and this is always a challenge. I saw other reviews about incorrect orders but so far mine haven't been incorrect abut just takes a while to make sure it's right.

    Overall a cool spot and lots of potential. Please add better ingredients!

  4. Came back here. I have to give them a 5. Regardless of the parking situation, everything was even better the 2nd time around. I ended up getting the Mario Stack, a Vanilla, Chocolate, and Cookies 'n cream milkshake, and fries.

    I'm also happy to hear that the business has been booming here.  This fat sandwich place definitely has potential to be a hit market against Fat House in Belleville. Get ready North Jersey, fat sandwiches are making an ambush in the area!
