The UCB theater in Chelsea is a great place to watch some improv comedy. You might remember the popular "Upright Citizens Brigade" TV show from Comedy Central. Those performers went on to start this theater as a showcase for other emerging improv performers. Tickets range from free to $10 - check out the website, ucbtheatre.com, to find shows and reserve tickets via email. My personal favorite troupe is "The Swarm," who perform Friday nights. You might also check out one of UCB Theater's "Cage Matches" - two improv troupes battling it out. UCB Theatre serves cheap beer and sodas, and there are plenty of cheap places to grab a bite nearby.
