Polar Bear's Café

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.
