RDV (short for rendezvous), a hidden subterranean playground tucked away below French restaurant Bagatelle, is filled with all the gleaming wood floors, tailored animal pelts, oriental rugs and claw-footed leather armchairs required for finer living. A baby grand piano and antique foos-ball table enhance the affected-retro vibe. New York does love its secret underground lounges. Almost a little too much, by our count, but it's hard to pick on RDV. Too pretty!
