One bar in the Japanese city of Utsunomiya has become famous for engaging in the best sort of monkey business. Patrons of the Kayabukiya Tavern, a traditional Japanese sake house, can monkey around with a troop of trained macaques while eating and drinking. A small band of the little simians, decked out in adorable matching costumes, marches through the restauarant, causing sounds of sheer delight from stunned patrons to ripple throughout the establishment.
