When I was much younger and living in Chicago in the 90's, I was very busy trying to figure out what I was and what I wanted to be. I had a brief romance with the occult (not the cat killing, or blood drinking kind) and there was a particular book store that fed my curiosity. The Occult Bookstore had a small sign, was dimly lit and loads of leatherbound and elegantly decorated books on the dark wood shelves. The place had no regular hours that I was aware of; it seemed that you had to know somebody to get in. Being an obvious product of the suburbs, I never managed to figure out how to get in there and unlock the secrets to a new universe.
It looks like they have a website now. It really seems to have taken a lot of the mystique out of the place. I'm also 15 years older and work with dead guys, so my perspective has changed a bit.
