How do you get into The Box in NYC?

I'm curious, how exactly does one gain access to the elusive "The Box" in the bustling metropolis of New York City? Is there a secret handshake or a code word that needs to be uttered? Do you have to be a member of a certain exclusive club or possess a rare commodity? Or is it more straightforward, perhaps requiring a reservation or simply showing up at the right time? I'm intrigued to know the process and the steps one must take to unlock the mysteries within this enigmatic location.
