San Francisco's nightlife is as diverse as San Francisco itself, and each district's selection of bars, clubs and lounges has its own distinct flavor. For electronic music clubs, hip-hop or chill art lounges, head to San Francisco's SoMa neighborhood, while the artsy Mission district is primed for everything from dive bar hopping to intimate dance space, an alternative to the city's larger clubs. On the flipside, the Marina District sports decidedly slicker (though no less debaucherous) bars. Gay-friendly bars and clubs exist all over the city, with the Castro, SoMa, and Polk Street areas leading the way. San Francisco's North Beach is open until the wee hours with neon strip joints and cool hideaway bars, and rowdy clubs. It's all available here with SanFrancisco.com's district-by-district guide.
