I just did the one in Nashville. It was a lot of fun, but it was very expensive (~$35), and they also made us solve the puzzle with a bunch of strangers (in order to fill up the room entirely).

The good part of this is that they're making $280 per hour (8 x $35) off of their escape room, and at those prices, there should be many, many more of them soon (which will bring down the price to its equilibrium, which I assume is far lower).
