Ask anyone in nightlife why a club all of a sudden becomes THE spot, and the answer is always 'the crowd.' The best venues also have the best people to facilitate the door, who can curate the room and bring in the right crowd for the vibe. While it seems like their only job is to size you up as you approach the ropes, there's much more to understanding how to work a door. We set out to ask the gatekeepers of our favorite clubs about the best nights at the venue, what the owners are like, and the outfits no one should ever wear when hitting the best clubs in town.
