We went to a paid show the other night, and the waitress put our checks onto one bill and tried to get a 300% tip when everyone else paid in cash and I paid with a credit card!
The comedy acts are usually pretty good there, but the food is so-so and definitely over-priced. I'd say to hit up one of the other diners in the area before or after the show, instead, but most nights, there's a two-item or two-drink minimum per person, anyway, so it can get pretty expensive in a hurry.
