In the latest issue of Shokugeki no Souma, Erina's father talks about food that only selected people can enjoy, but didn't really pinpoint what it is. I'm kind of confused because nobody from the spectators asked what kind of food it was? He only said that it's some kind of artwork or something like that.
But because her father has a dark atmosphere around him, I can't help but think that it may bbebe some taboo/forbidden style of gourmet.
