Alcatraz ER, styled like a prison hospital, sounds like a recipe for bad service and crap food, but expect sausages styled as human intestines and penises. Bad customers have their trousers pulled down for a lethal injection from duty nurses.

If you want to be spoon fed, OK Bokujo sounds like an otaku‘s dream, combining cosplay with barbecue, with waitresses dressed as anime characters grilling chunks of meat before blowing on them gently and then feeding customers.
