Tucked behind a seemingly non-descript hotel bar, this club is easily recognized by its dozen or so David LaChapelle works featuring stars from Tupac to Britney Spears. Given the venue’s location inside of the Gramercy Park Hotel, the crowd is surprisingly well-curated, thanks in part to its status as an after party destination for events like New York Fashion Week shows. To get past the velvet curtain, know someone who has a list—or prepare to pay up.
