Why is Sacha Baron-Cohen pretending to be a chef and how is he convincing a food critic to eat 'human flesh?'

to his meal that 'Rick's prison-themed cuisine 'has the potential to earn a Michelin star.'

With unusual delicacies such as his starter of a 'beans on toast medley' followed by the disturbingly-titled 'anally-aged veal in a strawberry prophylactic' which Rick reveals was inspired by how veal was smuggled into his prison way back then.

Sacha is truly a  master of deception and enthrals Bill with an elaborate a backstory of how he learnt to cook in prison with limited resources and knowledge.

If this didn't stir up some massive concern, then 'Rick's' final dish surely should have had the food critic questioning everything. Bill is then served a  'filet of vegetarian-fed Chinese dissident and cauliflower purée'.  When talking his guest through his dish, Sacha posing as Rick convinces him that he is tasting 'ethical, human meat' sourced from a farm in China. 

Despite Bill's initial misgivings, thanks to 'Rick's authoritative and convincing approach, he decides to give the 'Chinese dissident' dish a go. But, what did he think?
