Tao was my first clubbing experience in Vegas, and while it's not generally my style, we had a fantastic time.
We were in the VIP line at 9:30 where we met some guys who had been there a bunch of times, so they showed us around all the rooms. The decor was awesome. Being from New York, I'm not a fan of the big, swanky clubs, but it was definitely fun on vacation.
Drinks were strong, especially for it being open bar (for girls) till 12:30. Dance floor was packed, but there was still a lot of room to move around elsewhere. Music was great.
I liked that the bathroom was upstairs so you could get a view of the whole place. Worth a go while in Vegas.
