Isekai Izakaya: Koto Aitheria no Izakaya Nobu

It's an odd setting. A small diner with the back entrance in modern day Japan and the front entrance opening up in a medieval fantasy land. Most of the fantasy inhabitants are overwhelmed by the Japanese style food. There's a recurring theme of people coming in to harm the diner, but end up eating and loving the place. The cooking takes a prime position in the show, and eating usually ends up sending the diners into ecstasy. I'm not a huge anime fan, but shows like this keep me watching and looking for similar types.
