The Archipelago called the Islands of the God of Cookery, or more colloquially "The Stew", rests in the Windward Sea off the Western Continent of the world known as Central. Of the over 8,000 islands in the Stew, most are for the cultivation of ingredients necessary for the achievements of the Culinary Academy, which dominates the Island of Nonpareil.
Isekai Izakaya: Japanese Food From Another World
Ryōri no Tetsujin (Iron Chef)
Isekai - there's a bunch of different kinds of Isekai. The world of Central is more realistic - character classes are recognized, but there's no Status ability that shows people their RPG stats. You have some choice on how you got to this world, and each of you received new abilities in the form of a character class or non-human ancestry from the God of Cookery.
Cooking Duel: Very much like Shokugeki no Souma (Food Wars!) contests.
Heroic Fantasy - The Stew exists in the world of Central, which probably has a few manga written it all by itself, and serves as a backdrop for the Cooking stories.
