It's another one from the twisted and brilliant imagination of London's Miss Cakehead: diners were given surgical gowns and gloves, and feasted on trompe l'oeil dishes the they dug out of a rib-cage that appeared to be connected to a screaming victim.
Guests ate with surgical tools, and there were pill-bottles full of candies strewn around the "operating theatre."
