I must have been bad because we always called it Nicadish.Loved Picadish.
Me Nan used to take us of a Saturday.
Fizzy float. A scoop of ice cream in a glass of orangeade or whatever.
Mince and tatties. The mince so thick that it was, well, as thick as mince.
Oh, and I reckon I was well into my thirties before it dawned on me that Picadish was a kind of pun name for a self service restaurant. I never realised that. It was just a name to me.
