Nonno's Ristorante Italiano has served La Mesa's Fletcher Hills corridor from Baltimore Drive since 1998, producing handmade Sicilian pasta and fresh seafood in a neighborhood trattoria format. The wine-and-beer list pairs regional Italian bottles with local San Diego craft selections, including brewery-direct pours from Helix Brewing Co. produced in the same La Mesa ZIP code. A dedicated catering phone line handles off-site orders separately from the dining room, serving corporate lunches, event buffets, and family-style Italian spreads across eastern San Diego County. Sunday and Monday closures convert the restaurant into a private event space seating 15 to 40 guests on a fixed multi-course Sicilian menu. The catering program delivers lasagna trays, manicotti platters, and fresh seafood spreads for events across San Diego County, adding Sicilian volume to a La Mesa catering scene that also includes Aromas of India. The kitchen produces fresh pasta in-house for lasagna, manicotti, and rigatoni plates, while filet mignon and seasonal fresh-catch specials round out an Italian menu that extends well beyond the standard red-sauce framework.
