My four stars are due to us being at Rok for their opening weekend: Labor Day, 2008. Katy Perry performed! The whole place was filled with celebs! So I'm taking it from the other Yelp reviews that my experience might not be typical.
Rok is the smallest club I've ever seen in my life. I know people that have bigger bedrooms than Rok. But that's okay! Just helps me mingle more easily! The drinks are good...not exactly strong, nor cheap, but comparable to other Las Vegas clubs.
The bouncers didn't seem to know how to handle the crowd outside...the lines were a fiasco...but it was probably due to the Opening.
