The lines that form along the sidewalk outside this Clarendon club every weekend give an idea of how popular it is. The ground floor pulses with live music or DJs, and twentysomethings come dressed to impress. The rooftop pavilion, open May through October (weather permitting), draws a more laid-back crowd. On Tuesdays, the club opens up for Swing Night, with lessons and open dancing. The club is open Friday nights all year as well as Saturdays when it’s not privately booked. During rooftop-friendly weather, it’s also open Wednesdays and Thursdays.
