The place is a little different from the outside, just a shop that has paper covering the outside (I'm sure to keep people from just looking in as opposed to going in). But he did have a nice selection of items from the KGB and other items there as well. He is very eager to show you his collection with some may find to be a bit pushy or rude, but I honestly think he is just motivated to show his crowd the items in his store. His English can be difficult to understand at times, but he gets the point across.
I think most people that gave the place poor reviews is due to them expecting a museum like the Smithsonian. It is in a smaller shop with 2 or 3 rooms, but he is anxious to show you his items and they are arragned very well. I liked the fact that he also let us put some of his props/items on. Good times over all. Glad we went!
