Natural speed please
if you live in the UK and know don't spoil it for others. There is a plaque above the shop.
Why is the shop famous?
I'm willing to give hints for the guessing game. Try not to cheat. In the past it was a grocer's shop. The owners lived above the shop.
But there is more to it than that. If you know for definate wait and give others a chance. The shop is not famous for what is sold there.
What else could make it special?
Could there once have been an iron in there? (a cryptic clue).
As I said it was a cryptic clue. If you are young you won't understand the clue but if you are in your 40s or older it might be easier to guess.
Some soviets might not have liked the iron that was in there. The iron started cold but got warmer over time. I think you can answer now:)
Did you cheat Mike?
Were my clues that easy?
Now what might a shop have to do with an iron lady?
It was where she was born, or rather where she was brought up (she was possibly born in a hospital).
Her dad owned the shop which sold vegetables and she and her family lived above it when she was a child.
