Hunger based dining experience

Have you ever noticed that food tastes better when you're hungry?

I wonder whether that presents an opportunity for a hunger based dining experience that relies on this fact.

A simple method might be for a restaurant to ask customers to, in advance, take a short survey regarding their eating habits, and then recommend the timing of their last meal before their reservation. The timing would be to maximize the food-improving hunger.

A more elaborate scheme would involve guests at the restaurant being fitted brainwave monitors that could measure the guests's hunger and so present food at the optimum time.
