OVA
At the bottom floor of the building with a dog signboard, in the shopping district near the office street, there lies a cafeteria called "Youshoku no Nekoya," that has an illustration of a cat on the door. It's been open for fifty years and has satisfied various salarymen from nearby offices. Despite it being called a Western cuisine cafeteria, it also provides other varieties of menus. For the people of this certain world, it's their one-and-only special cafeteria. There is, however, one secret to "Nekoya." The cafeteria is closed to the public every Saturday in order to make way for special guests. When a bell rings, customers from different places of birth and races appear who ask for mysterious and delicious dishes. They are actually the same dishes served to the salarymen, but these special guests find them to be more exotic than to what they are used to. As the cafeteria aims to serve masterpieces, it is usually referred as "Isekai Shokudou." And so, the bell rings again this week.
Summer 2017 Anime
The story is set in the year 2015, during the final era over which magic still held a strong influence. The humanity survival and security organization Chaldea was established to observe the world that can only be seen by magic and the world that can only be measured by science; as well as to prevent the final extinction of humanity. Thanks to the efforts of many researchers, the path of human history has been ensured for 100 years into the future. However, without warning, the realm of the future that was under constant observation by Chaldea vanished. The extinction of humanity in 2017 was observed—no, confirmed. The apparent cause of the extinction was in the Japanese city of Fuyuki in 2004. In that city, there was an "unobservable realm" which had never existed until now. Chaldea issued the Grand Order for a "Holy Grail Expedition," to investigate, uncover, and possibly destroy the singularity that apparently will cause the extinction of humanity.
