Great show especially if you have kids. Small venue so it's nice to have an intimate setting for people to see the tricks up close.
The show is one hour in length but it is fast-paced so he packs in a lot of things in that time span. There are a couple of parts that involve audience interaction.
Show up an hour before start time to line up (if you have general admission tickets) if you want to be front row in the general admin seating. One person in your party can hold your place in line for 30 mins or so while other folks in your party walk around. That said, it's a small venue and most seats have a good view. Premium seats are up front and have a table if you want to have drinks.
Get the groupon for this if the deal is still available. You'd buy the groupon then call the box office, mention your groupon, and reserve your date. You have to reserve the date in advance to guarantee your seat. If you wait until the night of to reserve your seats, then there is a chance it gets sold out because it is a small venue.
