The Western Restaurant Nekoya is beloved by its local Japanese patrons. The establishment's ongoing success stems from its delicious Western and Japanese cuisine, as well as its upbeat head chef, "Master" Tenshu. While the restaurant appears to be closed on Saturdays in Japan, it is actually the day Nekoya travels to the Other World to welcome guests craving foreign food. From castles to forests, the "Restaurant to Another World"—as its customers call it—ventures far and wide. Nekoya's varied and unusual clientele can expect to be welcomed by one of two dedicated waitresses: the polite demon waitress Aletta, or the mysterious elf Kuro. As both returning and new customers fill the establishment with tales from their respective lands, Master and his team ensure that everyone experiences a mouthwatering adventure of a lifetime.
