The comedy troupe
SAK got off the ground with a long-running contract at Disney. In 1990, they moved to their permanent home on Amelia Street, where they now perform several different shows per week.
The show I saw was the Thursday-night "Duel of Fools," basically an improv sports night: two teams, competing in various improv games. I generally enjoy this type of stucture, and the comedians were quite good at their jobs. I don't know if I would agree it's worth $13, but at $5, it's a pretty good night out.
One caveat: I am under the impression that this is a Christian group of performers. There's nothing wrong with that, but those who prefer a little more raunch to their comedy won't find it here.
