Cannibal restaurant in Germany?

Ads for a new Berlin restaurant called Flime are requesting people to donate body parts for hearty meals. Naturally, people are flipping out. Of course, whether this is all a hoax remains to be seen. I bet it's a (rather provocative) prank. From The Guardian (sculpture by Leonhard Kern):
 Wikipedia Commons 0 0A Leonhard Kern Menschenfresserin "Members declare themselves willing to donate any part of their body," the advertisement reads, adding that any resulting hospital costs will be taken on by the restaurant. They say they are also looking to employ an "open-minded surgeon".

The location of the restaurant – if it exists – is being kept a secret, as is the identity of the owners and investors behind it. As a foretaste of its menu, Flime is suggesting traditional Brazilian dishes such as bolinho, which it describes as "fried tatar balls with a sweet-sour dip", or feijoada, a main course consisting of "various pieces of meat with black beans and rice". It does not specify what type of meat is used.

The restaurant cites as its inspiration the indigenous Brazilian Waricaca tribe, which once practised the ritual of "compassionate cannibalism", or eating parts of the corpse of a loved one to emphasise the connection between the living and the dead, which was said to help with mourning.
