Pro:
Gorgeous facility.
Open bar for "ladies" from 9:30-10:30pm. "Ladies" free, guys $15. Get on the guest list by walking around with a group of girls to attract promoters. Line up by 9pm to avoid stupid douche bag bouncers and lines.
Music was by DJ Vice that night and he was amazing.
3 dance floors!
Con:
Beware of the "open bar" as their disgusting generic "Vodka" gave me a massive hang over the next day.
Place got so packed by 12pm that you are dancing shoulder to shoulder.
Conclusion: You need to go to Tao if you are in Vegas. Tao is a truly unique clubbing experience.
