A boom-town club on a busted SoMa block, Monarch has a plush parlor bar and cozy library bar on the main floor, downstairs black-box dance hall ($10 to $25 admission, cash only), killer sound system and party-ready DJs. Upgrade from merely happy to 'amazing hours' weekdays 5:30pm to 8:30pm, when contortionist comedians and circus burlesque acts often perform over the bar.
