Worst theater I've ever seen, by far.
If I could rate this as 0 stars, I would.
I attended the Killer Karaoke show with my wife and a few of our friends on the evening of April 29, 2011, after having purchased tickets on LivingSocial. As mentioned by other reviewers, we were surprised to have to pay $28 extra for parking, taxes, and gratuity. My friend who hadn't bought the LS ticket paid $60 at the door.
Horrible show. We kept waiting for it to get better - for the actors to make a joke of how bad the first part was. The room was packed - everyone we talked to had purchased the LS tickets. LivingSocial needs to screen their offers better than this.
The only saving grace was the food, which was good (since the show is at the Sheraton hotel near the Galleria).
If you already have tickets, don't waste your night, and additional $28 on this.
