When VIPs with a liquor locker come in the restaurant, they can tell the cocktail server their name and give them the key to unlock their bottle. Anyone can rent a locker, but there are only a couple left. Each locker is $800 for a year plus the cost of any booze you decide to load it up with. The liquor is purchased at cost from barleymash. They have a concierge service to provide you with liquor recommendations you might enjoy.
