Seventeen or eighteen years ago I went out to a restaurant in Toronto that had no menus and would (apparently, as told to my eight-year-old self) make anything you ordered. I don't know if this place is still around, and I remember little else about it, but I wondered if this rang a bell with anyone? Perhaps there are a number of places that fit this meagre description, but I figured I'd give it a try regardless.
For the record, I ordered pizza. Adventurous, I know.
