It's worth the effort trying to find the place. It's very small but it only costs a couple of quid to get in. We were given a torch each to take round with us which was fun and useful. There is lots and lots to see here and we were the only people in at the time we visited. There is all sorts here. Clothing, posters, examples of food, etc, etc. There's even an air raid shelter that you can sit in and a small gift shop. You basically follow a route through corridors that are packed with World war two items and it is very interesting. I would allow about an hour depending on how long you want to spend looking at the items.
