Nekoya, a Western-style restaurant nestled in an obscure Tokyo shopping district that goes by the name of Nekoya despite offering both Japanese and Western cuisine options. It's open during normal business hours but closed on holidays and weekends. However, there’s a secret twist: on Saturdays, it transforms into a magical realm where elves, dragons, animal men, and other fantastical creatures visit and dine at the restaurant. Many of them become regular patrons.
