The restaurant is a concept restaurant with the theme of "prison". With various surprises from entering the store to leaving the store, it attracts customers to the "dark prison world". Menus such as the poisonous "original experimental cocktails" poured into beakers, flasks and graduated cylinders are also characteristic. Currently, there are a total of 8 stores, 5 in the Kanto area and 3 in the Kansai area, centered on Tokyo.
In this plan, the Shizuoka store will open on July 25th and the Utsunomiya store will open on August 2nd. In the future, it will be opened in each city as an amusement spot where young people gather.
