This is a great family show. I highly recommend seeing Penn & Teller if you've never been. This is my second time and they're still great. They have been in Vegas for a very long time and it's due to the two of them changing their show so often. Penn & Teller have been working together for over 40 years and it def shows in their performance how much fun they have together.
The awesome thing about the duo is that they typically show you one or two tricks and how it is done, which is amazing because magicians rarely share their secrets. They perform magic but they are also very funny together and they get the audience involved. The best thing about the show is how they both stick around after their performance to take photos with the crowd and talk with everyone!
The theatre itself is not too large, I didn't feel like there is a bad seat. There is a pre-show you can enjoy if you show up early. There is a full bar, but no snacks for this show.
Overall, I love Penn & Teller, they are such humble and amusing men!
