The show is hit and miss. I've gone here on a couple of Saturday nights where I didn't laugh at all and then also where I laughed the whole night.
(Also experienced the same feeling on their 6$ pro/am Wednesday nights).
It's like Comedy russian roulette. I leave here either loving or hating the show (which I'm okay with given that tickets are pretty cheap).
They are also a bit picky about making reservations.
