Two eyes peer out of a small interior window on the far wall of the pizza shop, speakeasy style. A moment later, a plump and warm foil packet slides through to you.

Within walking distance of three schools, the shop attracts lines of students, sometimes stretching all the way through the screen door and into the parking lot. Teachers, too, have been known to dash over before classes start for a pencil-box-sized slab of thick pepperoni pizza. Hey, breakfast is the most important meal of the day, right?
