Checkmate NYC

Checkmate is a members-only on-premise swingers club on Manhattan's East Side for couples and single women, and single men are never admitted. New guests need an approved application with photos plus an RSVP, and there are no walk-ins. It opens Thursday nights and on Friday and Saturday nights, with an LED dance floor, mirrored playrooms, showers, attended lockers and a BYOB bar. Guests must be 21 or older and follow a strict dress code.
