For Sicilian-Italian deli sandwiches and New York-style pizza in La Mesa, MammaMia Deli Market — Gino & Gianni's Pizzeria operates a dual-concept space at 4231 Spring Street near La Mesa Village. The Sicilian deli launched in December 2024 and expanded into the adjacent pizzeria in October 2025, building an Italian grocery-and-dining compound in the same La Mesa Village orbit that includes trattorias like Nonno's Ristorante Italiano. The deli side stocks imported Italian cured meats, cheeses, Panettone, cookies, and wines, while the kitchen produces signature Schiacciata bread, meatball subs, and torpedo sandwiches from scratch. The pizzeria runs 18-inch pies and by-the-slice service from a double-deck stone oven imported from the East Coast, targeting the crisp, foldable crust profile associated with classic New York slice shops. Hand-painted Godfather murals, fresco-style ceiling artwork, and custom pizza chandeliers transform the dining room into a theatrical Italian-American setting, adding a visual dimension to a Spring Street dining corridor where Mario's de La Mesa delivers its own decades-long culinary identity. The 18-inch New York-style pie requires controlled dough hydration, a multi-hour cold-ferment cycle, and a double-deck stone oven calibrated above 500 degrees Fahrenheit to produce the foldable, crack-on-fold crumb structure that defines the format.
