For a small, intimate show, Stage Door Theater is such a fun choice. I saw Shear Madness here in 2009 and absolutely loved it. The show itself was hilarious, with great audience interaction and fun seating options. While I'm sure the seating may get changed up a bit for each run, my girlfriends and I sat together at a few small round tables near the front. There is also a bit of stadium like seating near the back.
As mentioned, this is the perfect venue to be super close to the action on stage and actually interact with the actors. In Shear Madness, one of the characters (police office) came out to the bar area during intermission and continued to interview the witnesses. I really appreciate small venues like this that show kitschy shows. Here's hoping I'll catch more cool shows at the Stage Door Theater!
