Ladies nights have long been staples of nightclubs and bars. Get a hen party started and the men will follow. Getting said hen party started in the first place is the hard part. Martinis and manicures, a promotion NY-based Beauty Bar claims to have originated, works like a charm, though. Where else can a girl get her nails done while simultaneously getting hammered?
