After getting his sister devoured by a dragon and losing all their supplies in a failed dungeon raid, Lyos and his party are determined to save his sister before she gets digested. Completely broke and having to resort to eating monsters as food, they meet a dwarf who introduces them to the world of dungeon meshi, delicious cuisines made from ingredients such as the flesh of giant bats, walking mushrooms, and screaming mandrakes.

Translation of: Danjon meshi.
