Hmm, Where do I begin? I first attended a show at Dad's in mid-2005. I've been there every week ever since. In addition to the quality shows and pure genius improv, the casual, comfortable atmosphere makes you feel right at home from the moment you step through the door. The people there are amazing -- both on and off-stage. The humor is creative and intelligent, with just the right amount of quirk. It's always a great time. There's nowhere else quite like it. Just be warned that you'll feel a strange gravitation to return as soon as possible.
Pros: Price, People, High quality entertainment.
Cons: Just don't leave valuables in your car.
