Excellent food --- best I've had in Vegas. And pretty much the only reason I'm going to give Tao 2 stars.
WARNING -- if you are a dude, and plan on having dinner with several dudes (i.e. bachelor party) at Tao, don't count on getting line passes to get into the nightclub. I went with three friends on Sat, 4/21, and after dropping $400 on dinner, we were informed by the HR manager looking hostess that we couldn't get line passes because we "threw off the guy to girl ratio" at the club. That's about the worst customer service I've ever experienced in my life... way to take care of your customers! We might as well have eaten at some fast food joint and started waiting in line at 8pm with the other sunglasses wearing jackoffs that infest Vegas these days.
Oh... and apparently K-Fed was there the same night having dinner with his posse.
