Unusual Restaurant of Mistaken Orders

In Japan, there is an unusual 'Restaurant of Mistaken Orders' where waiters with various dementias (Alzheimer's and others) work. The gimmick of the restaurant is that no one gets upset about poor service and no one complains about the waiters - receiving something different from what was ordered is considered the norm here. Occasionally, the waiters forget where they are and what they should do, but polite customers always remind them. Those who have visited the restaurant say that they haven't spent time in such a wonderful atmosphere for a long time.
