There is a certain restaurant in one corner of a shopping street near the office district. The historical restaurant, marked by a sign with a picture of a cat, is called “Western Cuisine Nekoya.” This restaurant looks completely normal through the week, but on Saturdays, it opens in secret exclusively to some very unique guests. During these hours, doors in various areas of a parallel world open to allow customers of many different races and cultures into the restaurant. This “Restaurant to Another World” and its food hold an exotic charm to these highly diverse customers. This is a story of the heartwarming, once-in-a-lifetime encounters between our reality and another world, between the restaurant’s customers and its owner, and the food shared among them all. Note: Based on the eponymous light novel by Inuzuka Junpei.
