The Best Restaurant in Esquilino and Environs, Rome

This family-run hole-in-the-wall has been in business since 1890 and specializes in one thing and one thing only: porchetta, the slow-roasted pig that the town of Ariccia in the Castelli Romani is famous for. Alessandro, the fifth-generation proprietor, slices it thin and slaps it on a sandwich roll. For vegetarians and the pork-averse, there are cheese-and-veggie sandwiches.
