University Club Of New York
Seekers of sophistication (and old money) might have better luck at this, well, more established members-only club. Snag yourself a guest pass from a well-connected friend and remember the dress code: suits, dresses, or skirts and dress shirts or sweaters, or tailored pants with dress shirts and jackets, elegant sweaters or scarves of equivalent formality.
Elegance, dahling. Elegance!
University Club, 1 W 54th St.
