We have some tourist traps like that and they are pretty much a joke.
There is one in my city called the "spy museum" and it was recommended to take my dad and aunty there by my wife (when we first started dating) - even my dad couldn't feign interest, and he had got excited over a type of drain pipe... :D
Haha, that is funny. We have a place up north called Mystery Spot. I haven't been there since I was a kid.
