Isekai Izakaya "Gen"

A pub that was supposed to be in a certain place in Kanto, "Gen". I opened the door one day and it was connected to the city of Parisia, the Kingdom of the Eastern Kingdom? Individual residents from a foreign world such as falling monks, warriors, noble female knights, daughters of noisy famous aristocrats, etc. all visited the peculiar izakaya which they've never seen before, and gradually they'll become fans of the dishes.
