Italianissimo Trattoria on Chula Vista's Third Avenue serves Romana-style Italian cuisine from a sit-down dining room at 323 Third Avenue, in the heart of the Third Avenue Village district. The menu builds around fresh pasta — gnocchi with gorgonzola and pesto, tortellini alla Romana, and eggplant Parmigiana — alongside a full bar and an extensive wine list with a corkage option for personal bottles, a wine-forward approach to Chula Vista Italian dining that resonates with the regional wine culture explored by Baja California Wine Tours. Thin-crust pizzas baked in a dedicated oven share the menu with antipasti like burrata and fried calamari, each plate designed for the kind of multi-course Italian progression that anchors a Third Avenue evening. Outdoor seating accommodates pets, and a seasonal catering menu extends the kitchen's reach to private events — positioning Italianissimo among the Chula Vista restaurants that draw destination diners, including guests staying at the nearby El Primero Hotel on Third Avenue. A San Diego County Environmental Health inspection score of 95 out of 100 covers the trattoria's compliance with California Retail Food Code requirements for pasta preparation, pizza-oven sanitation, and bar-service hygiene protocols.
