This square pepperoni pizza is a Detroit-style pan pie with a thick, airy base, a caramelized cheese edge, and pepperoni layered under and over the cheese. Square Pizza Co.’s version is distinguished by its fried cheese perimeter and light, open crumb that keeps the slice from feeling heavy despite the thickness.[4][2] When served, the crust is crisp on the bottom yet soft inside, and the pepperoni cups pool crispy edges and savory fat that melds into the cheese. Local rankings frequently cite this pan pizza as the defining item at the shop and a leading example of Detroit-style pizza in San Diego.[4][2]
