Doubles is like the closet to Narnia, or Madeleine L’Engle’s tesseract: breach an unassuming door inside the Sherry-Netherland hotel, descend the lushly carpeted stairs, and you will discover a more genteel world than the one you left behind. The private club has the magic of sophistication, thanks to standard-bearer and proprietor Wendy Carduner. From extravagant holiday events to impromptu late-night after-parties, members share a lifetime of memories among the shades of claret decorating the main dining room. This bastion of old New York celebrated its 30th anniversary in 2006, and has maintained its reputation as a kind of pied-à-terre for generations of high-society denizens. Its longevity proves its status as the best safe haven from the grinding city—all the more so as, situated a full story below Fifth Avenue, there is no cell phone service. For that and many more reasons, we have always RVSP’d yes to Doubles’ invitation to dine, dance, and mingle.
