All of the 5 star reviews are right...go see this show!
We got a Groupon for this and while it wasn't clearly stated on the ticket, you can call and make reservations. We didn't do that, but luckily we were still able to get in. The ushers direct you to a seat, but we asked to be seated elsewhere and were accommodated. We sat towards the back and didn't have any trouble seeing.
We went in a little skeptical, but we were blown away! He does a meet and greet afterwards and since we sat in back, we were able to get out quickly and we're first in line to meet him. He wrote down the number I picked between 1 and 100.
Fun way to spend a couple of hours!
