This is the best sci-fi/horror/fantasy genre book store in San Francisco. Regular events such as signings/readings and a hypo-allergenic hairless cat named Ripley. What more could you ask for? The prices are reasonable for collectors, too. Where else would you find affordable rare Clark Ashton Smith volumes? Very author friendly, if you happen to be in town... Drop by. In addition to having such a great selection of new and used books, the service here is beyond excellent. I once ordered some books through their website because they weren't currently in stock and I didn't have time to go in there to order in person. When the books came in, they called me to let me know - and when they discovered that I worked in the City, one of their staff members actually drove to my office to deliver the books in person! I was absolutely amazed by that level of service.
