Shows vary in nature, but be ready to participate in the show you attend. Wallflowers are not welcome at the Improv Asylum, where at any moment you could become part of the act. The small stage, set up in the manner that Shakespeare would commend (theater in the round), is surrounded by seats that allow the interactive fun to have you quickly on your feet and in the action. When you are comfortably seated, your contributions are expected because much of the improv performed is based on audience interaction.
You may want to leave the kids behind, as the Improv Asylum is for a mature audience. Guests over 21 get the most of this experience, especially on Saturday nights when attending the 21 plus, 11:59 pm performance aptly named "Raunch."
The Improv Asylum does not serve food, but for those 21 and over, they do offer fun-to-lug buckets of beer to enjoy before and during the shows. And those buckets come in handy while watching because it's guaranteed that you'll have a cold one by your side at all times.
