This is one of those places that I crave. I went to college near by and would use Uncle Sams as a place to treat myself to some good grub and great leftovers. I love the Portabella Mushroom sandwich. Not sure how they perfected the marinade on the mushrooms, but it is perfect. The buns are light and fluffy, and that is a good thing. The fries are of the best out there.
The atmosphere is a dive, but the fact that you can watch someone cook your food, is a big bonus. It looks the exact same as it did 10-15 years ago and I like that. Clean? Maybe not, but still rather sit in their establishment than in a McDonalds.
I request to go here on special occasions because the subs are just right and fit that need of something greasy yet especially delicious. A sub shop that should be one of the WQED Pittsburgh Restaurant shows, for sure. Has hometown Pittsburgh written all over it. One of my all time favorites.
If you don't finish all your sub, take it up to the counter where you ordered and they will wrap it up to take home. The Portabella sandwich is even great cold out of a dorm fridge!
