Polar Bear's Café
Shirokuma Cafe revolves around a Canadian white bear that quits his boring job and starts a cafeteria near a zoo. He loves telling tall tales and always brags about himself. According to him, he was picked up by a human couple who owns a diner while he was drifting around on an iceberg.
Though he has lost all contact with his Canadian family, he has discovered a new home in serving the diners' clientele, thanks to the kind couple. His café is an embodiment of his personality. The place is always packed with many regulars, animals and humans, who are drawn by his charismatic magnetism.
