The real question is whether or not you would ever choose to eat at any of these places if you were not trapped in the Magic Kingdom. Most of us would not. Disney knows that time is money for most people at the park. It is not really feasible to leave the park for two hours to get a decent burger. So visit after visit, we pay way too much at restaurants that would never be able to do business on the outside.
But on the positive side, if that is the food of the future... it will be a cure for obesity!
