At the Gaslamp location of Prince Street Pizza, the pepperoni square comes on a thick, Sicilian-style crust with a crunchy edge, topped with tomato sauce, mozzarella, and dense layers of small cup-and-char pepperoni.[5][8][17] The dough is proofed to stay light despite its height, and the heavy topping of pepperoni creates crisped edges and pools of seasoned fat across the surface. Each slice eats almost like a focaccia base with a strong salty, spicy kick from the pepperoni, and the underside remains firm enough to hold in hand. Video reviewers and local guides consistently single out the pepperoni squares as the defining order here.[5][9][10][17]
