I cannot imagine why either. We have a place here in Romania which is supposed to be Dracula's castle. Scary stuff all over the place and the special beverage: vampire blood. This actually being a very thick red wine. And quite strong.
The rest of the props consists of funny things: plastic fangs, kitschy masks etc. I wouln't pay a dime to see this place (I was invited once by a friend and this how I ended up there), however they make constant profit. I really fail to see the fun in this.
Thank you for your comment. 🙂
