In general, you may not bring your own alcohol to Drag Brunch, with limited exceptions.
If you have a special occasion, and/or you wish to bring an important bottle of wine or champagne to PS Drag Brunch, this is possible, but you will be assessed a corkage charge of $20 per bottle to your table check on the day. You should definitely inform Guest Service if you intend to do this, so that you are not stopped at the door.
All other alcoholic beverages must be obtained from the venue.
