De Petrillo's is a Smithfield pizzeria and bakery that makes its own pizzas, calzones, and rolls alongside a lineup of traditional Italian baked goods—cookies, egg biscuits, wine biscuits, and more. They're known for the Original Pizza Party Tray, a signature item that draws regulars. The early opening hours (6:30 a.m. weekdays, 7 a.m. Sunday) reflect its role as both a neighborhood breakfast stop and evening dinner spot.
