Delicious in Dungeon is a unique and captivating manga that blends the thrill of dungeon crawling with the art of gourmet cooking. The story begins with the Golden Kingdom being sunk underground by a deranged magician. In his final moments, the king of the fallen kingdom offers all his treasure to anyone who can defeat the magician, sparking a rush of adventurers eager to claim the reward. Among them is Laios Touden, the leader of a small guild. His party is decimated by a fierce dragon that not only wipes them out but also devours his sister, Falin. Undeterred by their loss and the dangerous circumstances, Laios, along with his elven healer Marcille and halfling thief Chilchuck, returns to the dungeon with a desperate resolve to save Falin.

Facing the challenge of survival with no supplies, Laios proposes an unconventional solution: to eat the monsters they encounter in the dungeon. This idea leads them to cross paths with Senshi, a dwarf who specializes in cooking monster meat. Senshi’s knowledge of monster cuisine becomes invaluable, and he decides to join Laios and his companions on their journey, driven by his own desire to cook a dragon. Together, they embark on a perilous adventure, filled with strange and often dangerous culinary experiences, as they navigate the labyrinth in search of the magician, while indulging in the unique delicacies the dungeon has to offer.
