Heirloom's unlimited monthly pass provides aspiring toe-tappers with access to any of its 10 weekly dance classes and five nights of open ballroom dance. The hour-long lessons can be taken as often as necessary to polish and perfect moves. Rather than rioting, zoot-suit wearers can peacefully demonstrate during Tuesday's Swing Night, beginning at 7 p.m. with a lindy-hop lesson, with Charleston and blues lessons following on the hour. Wednesday night is Latin Night, with sultry steppers learning salsa, bachata, and Columbian cumbia. Thursday sees the uncanny yet danceable pairing of hip-hop (7 p.m.) and Argentine tango (8 p.m.), before dissolving into a passionate, bandoneón-fueled dance-a-thon. On Saturday, whisk your dancing shoes away to a rockabilly-tinged West Coast swing class, and cruise the subsequent sock-hop for a side-stepping showdown with Brad from HR. Dance partners are not required.
