Cave, The - As THE male strip club of Philadelphia, the Cave draws women from all walks of life. Mothers and daughters in animal print, buttoned up 20-somethings embarrassing their friends on birthdays and bachlorette parties (and cringing when the dancers get too close), and the giggly college girls crowd into this meat display on weekends. 18 to get in, 21 to get to the bar. After the show, much of the 21+ crowd spills out into Flow, the club with which it shares a building. Showtimes: Thursday at 8, Friday at 10, and Saturday at 8 and 11.
