Where to: Joe’s Pizza in Harvard Square.

Why: For a real New York slice, served until 3 a.m.

The backstory: In the late 1950s, Joe Pozzuoli came to the United States from Naples. He’d learned how to make pizza growing up in Italy, and eventually he opened the first Joe’s in Greenwich Village in 1975 at the corner of Bleecker and Carmine, back when the neighborhood still had the whiff of anti-establishment grit, and where everyone knew his name. It felt and operated like a dive bar, dark and simple, with late-night hours and zero frills.
