Alcatraz, the crazy old uncle of Japanese theme restaurants, kickstarted the trend about a decade ago by capitalising on everyone’s love of hospital food. The setting is a “medical prison”. You are the patient. The waitresses are dressed as nurses. They handcuff you, pretend to inject a giant needle into your rear, and then lock you in a cell. Occasionally, the staff will “accidentally” open your cell door and it’s your mission to go screaming around the restaurant in a wheelchair evading the outstretched hands of other prisoners [from here].
