Zappy Pizza on Chula Vista's Third Avenue operates one of four San Diego-area locations from a storefront at 1352 Third Avenue, placing it on the southern stretch of the city's walkable downtown dining corridor. The standard 14-inch hand-tossed pie comes in thin-crust and stuffed-crust configurations, with Supreme, Meat Lovers, and the signature Hawaiian builds outselling single-topping orders — a pizza-centric menu running on the same Third Avenue corridor as On Stage Playhouse's pre-show dinner crowd. The Hawaiian pizza — ham, pineapple, and mozzarella on the house dough — has built a repeat following among customers who rank it above comparable pies from national delivery chains. Walk-in counter traffic remains the primary volume driver over delivery, fed by the same neighborhood foot traffic that sustains independent storefronts — including Comics-N-Stuff — farther up the avenue. Stuffed-crust builds layer an additional three ounces of mozzarella into the folded dough ring, adding a $3.99 upcharge to the base 14-inch format for a finished pie that weighs roughly 2.5 pounds before toppings.
