Enter through the back alley and head up the stairs -- but first, you've got to get past the door staff. There isn't a guest list or RSVP policy currently in place, so dress to impress to up your chances.

As the name hints, a menu of sparkling wines and champagne cocktails gets the party atmosphere going.
