9. Spy Bar, Chicago
A $1 million renovation a few years back made this intimate River North party paradise sweeter than ever. Top DJs spin here regularly, and during Lollapalooza weekend in August, big-name electronic bands such as M83 spill into nighttime club sets. "Great vibe," says Seth Troxler. "Basically the only place I play in Chicago."
Fun Fact: SpyBar made local headlines last year when a patron punched a sprinkler and drenched the clientele. The dude claimed it was an accident, but security cameras clearly busted him as a vandal.
