We only went because we found a 2 for 1 coupon on the internet - http://www.vegas4locals.com/coupons.html
The show was only about an hour long and all set to 80s music to tell the story - which was pretty funny in and of itself. The dancing was fine, but nothing to write home about.
If you've never seen a topless show it is pretty amusing, to say the least. Compared to 'Jubilee' (just as cheesy) this was a modern twist on a typical burlesque show - no big head dresses here, just fangs. The tops come off and on throughout, some audience participation but nothing to be scared of.
Have a couple of drinks and be amused. Just don't expect to be wowed AND be careful not to laugh too loudly as you might attract the vampires' attentions. ;-)
