Polito's pizza is great. They have many different slices to choose from (all NY Style large slice), and I have never been disappointed. The garlic knots combo is a great deal, and on Monday and Tuesday they have a great deal on 2 slices. The pizza by the slice can be a little underwhelming (crust tends to get a little too hard for me) but their fresh pizza is nearly perfect. Everything on the menu is good, and the specialty pizzas are all fun to try. Went here all of the time when I lived up the road.
I would be wary of going late at night (around bar time), as this is a VERY popular destination for much of the campus bar crowd. Go during the day or in the early evening to miss the shenanigans of bar close.
