About San Diego
City overview
San Diego is the Southern California border city where San Diego Bay, Balboa Park mesas, Pacific beaches, and the Tijuana crossing make a compact but varied visitor map. Gaslamp Quarter, Balboa Park, La Jolla, Coronado, Old Town, North Park, and Little Italy cover the range from museums and tacos to surf breaks and harbor walks.
Food & drink
San Diego food is coastal and border-influenced: fish tacos fold fried or grilled fish into tortillas with cabbage and sauce, California burritos add fries to carne asada, carne asada fries pile steak and toppings over fries, and ceviche and uni show the seafood side. Little Italy Mercato, Liberty Public Market, Convoy District, Barrio Logan, North Park breweries, and La Jolla seafood spots add craft beer, wood-fired pizza, and Baja-style counters.
