A pizzeria located in beautiful Harvard Square, also known simply as Tommy's. It claims to be the "Home of the Sesame Seed Edge", although you can also get other toppings on your crust (allegedly; I've never seen it done). Their pizza is neither particularly tasty nor unique, but it does the trick (and is reasonably authentic to boot) at 3am when nothing else in Boston is open. It is crammed full of Harvard students every weekend night after the bars close and the parties let out.
