Haven been to this twice, both times for a bachelorette party. Cheesy music and dancing, buff rock hard bods... very good looking guys with accents... lots of yelling screaming and music... maybe not something you'd do every time you come to vegas, but a good time if you're with a bunch of your girlfriends and it helps to be a little more tispy and loose :)
Maybe if you're lucky you'll get a crotch in the face :-p jk
The decor of the theater was very minimal... all black, cheap chairs and tables, so don't expect much. I think they could do with some better furniture and design. Bar in the back was so-so and watered down. Save your money with that and just drink up before the show.
The Aussie men were also very nice and gentlemanly. When the show is over you are invited to order photos with them and when you're up there interacting with them they are all very nice, no sense of arrogance or boredom.
Well trained... why can't all men be like that :)
