I'm not actually sure what the name of this place is---as you can see, it has signs for two different names. In any case, it is just off 14th Street, within a reasonable walking distance of campus.
The key test of a pizza establishment that claims to be authentic New York style is whether they serve slices. These guys, to their credit, do. The instant gratification of a slice is hard to beat, plus it doesn't require a gang of people to help you finish off the pizza. This is pretty good neighborhood pizza---nothing fancy but it hit the spot. They also have a variety of other New York Italian sandwiches and Philly cheesesteaks.
