Dungeon Meshi - Story.
The girl Falin was eaten by a dragon in a huge dungeon. Now her brother Lai together with his friends must save his sister. Only the squad has no money and time to prepare provisions. They will have to cook their own food right in the dungeon - from the monsters living there.

Why it's worth watching. Trigger Studios has taken on the adaptation of the popular manga, which mixes a cooking show with adventure fantasy. It has previously worked on Cyberpunk: Running on the Edge and Honey in the Franks. The anime turned out to be incredibly beautiful: there are detailed backgrounds of multi-level dungeon, and appetizing depiction of dishes from a variety of monsters.
