If the Venn diagram of your perfect bar includes “tiki,” “uber-hip,” and “right on the edge of skanky,” this is your place. The Bikini Lounge has been around since the 1940s; it sits at the top of the Grand Avenue arts district, secure in its distinctive mix of retro and artsy, with some neighbors in the mix to prop up the working-class bona fides. DJs show up most nights, many playing vinyl. Tropical drinks galore, but it’s a place for serious drinkers, too.
