Isekai Shokudō: Yōshoku no Nekoya

Synopsis

There is a secret to Neko-ya, a very ordinary Western-style restaurant. It is that every Saturday, when the restaurant is closed, it is overflowing with "special customers." The customers, who are all different from each other in terms of birth, upbringing, and even race, are looking for the most ordinary Western food. But for them, it's a dish they've never seen or heard of before.
