At the Kayabuki restaurant in Utsunomiya, Japan, there are two costumed monkeys who are employed as waiters. Yacchan and Fukuchan wear wigs and masks and wait on tables in a restaurant that reviewers widely discount as having bad food and bad service (from the humans, not the monkeys). The video here is from a March 2010 visit to the restaurant.
