About San Francisco
City overview
San Francisco occupies a compact peninsula between the Pacific Ocean and San Francisco Bay, with steep hills, fog belts, cable cars, Victorian streets, and bay crossings making short distances feel different by block. The Mission, SoMa, Castro, Haight-Ashbury, Chinatown, North Beach, Marina, Pacific Heights, Sunset, and Richmond each sit in a distinct microclimate and cultural lane.
Food & drink
San Francisco food is neighborhood-specific: Mission burritos wrap rice, beans, salsa, meat, and foil into a full meal, sourdough carries a tangy starter tradition, Dungeness crab anchors winter seafood counters, and cioppino turns crab, clams, mussels, and tomato broth into a North Beach stew. Use the Ferry Building, Chinatown's Stockton Street, the Mission's 24th Street, North Beach, Fisherman's Wharf, and Richmond District Clement Street for dim sum, oysters, Irish coffee, bakeries, and roasters.

Getting around
Muni runs buses, light rail, streetcars, and cable cars, while BART handles airport, Mission, downtown, and East Bay trips using Clipper cards or mobile Clipper. Walk neighborhood clusters, use BART for Mission or airport moves, use Muni for Golden Gate Park and western districts, and carry layers because Sunset fog and Mission sun can sit 30 minutes apart.
