K-

My buddy said that when he and his wife ate at Tao the restaurant, they were given comp access to the nightclub by asking their waiter. When I ate there w/ my wife a couple of months later (early '08), we asked our server about going to Tao nightclub. He sent someone else by, she sat down and chatted w/ us for a few minutes (personally I think she just wanted to make sure we weren't butt ugly), and then put stamps on our hands. Pretty simple process. I don't know if this would work when just ordering a drink at the Tao restaurant bar or not, as my wife and I had a full meal.
