Went 2 years ago, and it's quite possibly the best show in Vegas!
I've always loved Penn & Teller, back in the days of P&T's Bull**** beginnings. I also relate to their politics, so that helps as well.
It's like a political venting session / stand-up comedy / magic show. Basically, it has everything.
If you don't like P&T's TV show, you won't like this magic show. Don't go there expecting to just see a magic show. They will swear and talk smack about the government and religion. Don't say I didn't warn you.
MILITARY DISCOUNT - when we went a couple of years ago, they gave us a 2 for 1 military discount. AWESOME!!!! 50% off?! That's the best deal I've seen for a show in Vegas. Hands down.
THE BEST PART -- you don't need a VIP badge to meet them after the show. They stand in the lobby of the theater to meet & greet EVERYONE, sign autographs and take pictures. GREAT GUYS!
