The Ghoul Restaurant (喰種 レストラン) is a secret society with a strict membership system. The members provide the bodies or the body parts of the humans themselves.
A special feature is the Dismantling Show. Members lure unsuspecting human "guest" to the restaurant, where they are ordered to shower and change into formal wear. These victims are then trapped in an arena with a human slave called the Scrapper, trained to kill them for the entertainment of the members. Afterwards, the bodies are prepared by the staff and served to the members. 
The primary Restaurant featured in the series is located in the 7th Ward, and was eventually destroyed by Kaneki's group. Other locations are known to exist, though it is unknown whether these are all the same organization.
- Taro-chan - Killed by Tsukiyama
- The Restaurant seems to be based on The Restaurant with Many Orders, a short story by Kenji Miyazawa. Kaneki mentions the story upon realizing the truth of the restaurant.
