We absolutely loved this place. It's slightly out of the way and you'll wonder if it's worth it, but it so is.
What is it? I know, we wondered the same. People all over the world have submitted notebooks filled with anything and everything and they're filed under key search words. You arrive, think of something to search on, your home town for example, and if you get results they bring the mystery notebook to you, plus one other. Get browsing!
Utterly absorbing, we were there for nearly two hours. Great stationery to buy too.
