Pen & Teller show was one of the highlights of my recent Vegas vacation. Their act had a few old (seen on TV) bits but a majority of content was new (to me at least). As another reviewer stated, Intellectually stimulating, the show is like myth busters for mostly debunking magic and psychic powers.
Very Unique and refreshing.
Also cool is how Penn and Teller both join the fans/audience in the lobby after the show for photo/autograph opportunities. I really liked that and had a chance to meet both of them. They were very nice and patient with everyone despite the overwhelming crowd and chaos.
I didn't do five starts because of repeated content I had already seen on TV over the years.
