Right around the corner from John's you'll find another pizza institution, Joe's Pizza. An unassuming dive that serves up pizza by the slice, Joe's found its legs in 1975 when an Italian immigrant from Naples opened up shop on Carmine Street. Only a few doors down from its original location, Joe's continues to dish out thin-crust pizza to the masses, often in the wee hours of the morning. But while the joint is open until 4:30am, this is pizza you'll want to eat at any hour of the day, whether you're inebriated or not. Purists at John's often opt for the plain cheese, but the Sicilian slices and squares – loaded up with extra flavors – have more than a few loyal fans.
