Pizza shops and Italian delis dominate the off-campus dining scene in Troy. There is a decent variety-you should be able to find whatever you want. For a greater variety, students usually hop in a car and head to Albany for some real restaurants and selection.
For the most part, off-campus food in Troy is the same as any other college town. The best (and most affordable) meals can be had at the pizza, Chinese, and deli places. There's nothing special or unique that would separate the restaurants in Troy from any other college town's food, with the exception of the Ruck's "wingburgers" and Troy Pub's home-brewed beer. If you can find someone with a car, the restaurants on Wolf Road in Albany are definitely worth the trip.
