For San Diego-style Mexican catering across La Mesa and the surrounding county, Sombrero's catering office at 5575 Lake Park Way coordinates orders for the regional chain that has operated since 1984. Buffet packages arrive in ready-to-serve party packs that include rice, beans, a full salsa bar with red, green, and chunky varieties, guacamole, chips, and hot carrots — a tray-format approach to the same San Diego-style Mexican menu served at sit-down locations like Casa De Pico in the Grossmont area. The chain uses generations-old family recipes across its 12-plus locations in San Diego County, and the catering arm extends that menu to corporate lunches, holiday parties, and private events with a six-person minimum order. The Lake Park Way office handles scheduling, custom menu builds, and delivery logistics for a catering radius that overlaps with the seafood-focused event menus at Anthony's Fish Grotto near Lake Murray. Catering trays feature the chain's California Burrito Supreme, carne asada platters, and enchilada builds assembled with hand-rolled corn tortillas, slow-braised proteins, and house-blended red and green chile sauces.
