The best pizza in the world can be found at Pepe's Pizza on Wooster Street in New Haven, Connecticut. No arguments. I've been going there for my entire life, and before that my parents started going when they were in college.
On a summer weekend you can stand in line for almost an hour. And it is worth it. This weekend we didn't have to wait too long in the cold, but long enough to do a sketch of the sign. Our family favorite is bacon and mozzarella. Such a treat!
