Breakfast

This is the breakfast to which Cathaber refers (here). Your teaser, should you wish to be teased, is what has this to do with HRH Prince Charles?
By the way, I had to watch Cath devour nearly the whole of this before my breakfast arrived, because the kitchen had to go to the bakery section of the store to stock up on baps of which they'd run out. It was cruel. I was wasting away.
