My first time in Vegas with friends and not family, we stayed at the Venetian and for some reason never went to Tao! The second time we flew in Thursday night and went to Tao for Industry Night. We probably arrived around 1am and just walked up to the doorman. He asked us if we were on a guest list, we smiled and said no and he let us in (prob a combination of us being girls + industry night).
The inside is Asian themed which is a little weird for me since I can actually read the Chinese characters pasted around the club. From what I remember there are 3 floors. We were on the second floor the majority of the time at a table. The table set up is a little weird because there is a velvet rope separating the dance floor with the table but it just gets annoying because you have to go all the way around to get to the other side and people just kept on pushing the rope around.
The music was a good mix of top 40, house, hip hop...although there were some old creepers lurking doing some dance moves from the '70s. Not sure if it was because it was industry night or what but the ratio of cute guy to cute girl was heavily skewed. Guess that's how creepy old guy found a girl to dance with. Gross.
