Lindell Boulevard, the broad street bisecting the Central West End, has never been a hip night spot, but the owners of Sol Lounge have breathed new life into the area with three massive floors of nightclub bliss. It's the perfect spot for A.D.D. club kids: If you get bored on one floor, find the nearest staircase and head to another. The main floor lounge hews to the swank club archetype, with exposed brick, low-slung couches, an impressive bar and progressive house music pulsating throughout. Up the stairs and through the bathrooms, then up another staircase, and you hit Reference, the club within the club. Up one more flight, and you're in the Attic, where you can people watch in a cozy corner or bust a move in the middle of the floor. The crowd is as diverse as you'd expect, and it's the only club in the west end with a 3 a.m. license. Keep an eye on their events, as Sol Lounge draws preeminent party starters like MSTRKRFT, Ladytron and Skrillex.
