Regarding the last review, the metal...

Regarding the last review, the metal bar "prison" is the smoking area which has to be outdoors since no smoking is allowed inside clubs in LA. The metal bars are meant to prevent people outside from coming in, rather than the other way around, so that people do no sneak in without paying the admission.

The dancers do enter the stage totally nude at the beginning of the second song (although some break that rule and few even never get totally nude). I find this nude entrance a plus since the anticipation and the "surprise" contribute to the excitement.
