Overall it's a different change of pace. I've read a few reviews and people who complain about the food or the story are missing the point.
The show depends on audience participation. That makes it work or not work. We had a good crowd of willing participants and people cheered others on. Our "Big Daddy" character from the audience just killed it. There was a dance scene with 5 or 6 guests on stage and one guy just took over the dancing and was funny as hell. If your show doesn't have a few people like that then the mood probably takes a pretty big dive. The cast seems genuinely interested in what they are doing.
