As a concept, I think they stumbled upon a great idea. Too bad there seems to be some cutting of corners.
I attended an afternoon show and the food was terrible. It was obvious that this was food prepared hours before, if not actually left over food from the day before: the fries were so dry you could be forgiven for thinking they were chopsticks, the spicy wings were rubbery, and the sauce they poured on top to make them seem fresh only made things worse. My wife's sandwich was soggy, so much so that she couldn't eat after a few bites as there was nothing to hold, especially since they hadn't supplied a spoon to scoop the gruel with!
Because I like the idea, I might try a later show to see if they serve fresh food then, but I have to say that my first experience was disappointing.
