I really like this restaurants ideas about stopping food waste.  Perhaps it will stop people over ordering and wasting food.  A 30% discount is pretty good if you eat all the food on your plate.  And if anyone thinks that this will cause overeating, wrong, it will get people to think about what they are ordering.
