Pepper's Pizza is a great spot for pizza on Franklin Street. It's got a casual laidback vibe. The staff is friendly and the pizza is quite tasty. I hear the Calzones are good, but I haven't tried them myself. Pepper's is a nice spot to go before going to a movie or before a night of barhopping in Chapel Hill. They also sell raw pizza dough so you can take it home and make your own creation.
