This has nothing to do with the shows here -- frankly, I have found them to be hit or miss. If you are willing to spend $5-$10 and sit through some comedy, you may find yourself laughing hysterically. Or you may find yourself wishing you sat on the aisle in the side seats so that you could sneak away without drawing too much attention to yourself.
This is about the venue.
When the UCB lost its garage-door-closeable home just south of here, it gained space. And a better (sort of) lobby. And more bathrooms. But it also gained a musty smell that sometimes sticks to your jacket even after you have left the show. If that happens to you, I hope you went to a show where you laughed a lot. Otherwise you got screwed.
