I'm surprised to see such a low rating. I have never had anything but the best experience at Fat Tommy's. The food has always been good and you can't beat the prices especially in Market Square. For reference, you could go across the square and get a sub at DiBella's, pay twice as much and get a worse sandwich. So for what it is, Fat Tommy's has to be the best restaurant around.
Let's just remind ourselves what Fat Tommy's is. It's a pizza and hoagie place with a bar and TVs. It's not gourmet, high end food. It's unpretentious and laid back and expectations should be set accordingly. However, there should be some expectation of attitude from the workers, first because their motto is "Fresh Food with Attitude" and second because you would have attitude too if you spent hours in front of a hot pizza oven. I can't think of one pizza joint where the workers didn't have attitudes. That suits me just fine though because I expect it going in. Perhaps the people with the negative reviews didn't realize this going in.
But when I'm downtown and want a slice of pie or a delicious toasted hoagie, Fat Tommy's is my first choice.
