Bowery Bliss (CLOSED)

These grimy digs on the Lower East Side are a choice haunt for rank-and-file members of the swinger lifestyle. But if you’re single and keen to mingle, it welcomes unattached men and women on Tuesdays and Thursdays to its cozy lounges and self-described playrooms for your rendezvous. There’s no booze, but there is free soda.
