Tao Beach is the newest addition to Tao nightclub in the Venetian in response to such high demand. But with a 4 bottle minimum (meaning a $2,500 tab), they should get more heat lamps. And also a better DJ.
I froze my ass off all night. And although I looked forward to watching people jump in the pool circa 2 AM (as promised by the bouncer, who tried to list reasons why the beach was just as cool as the lower levels), it never happened. The DJ was mediocre, the cups were plastic, and the bathroom was impossible to find.
My advice to you-- if you go to Tao, make sure to get a table downstairs.
