First off..... I know nothing about Harry Potter - except the very very basic stuff. That being said, a friend of ours has a son who is enthralled with Harry Potter and all that goes with it. I read that there is a Harry Potter shop at platform 9 3/4 at Kings Cross Station. All we want to do is take a photo and perhaps purchase a t-shirt for him. Can anyone verify that there is indeed a shop at the platform and give me a bit more direction on it ?
