Bookmaze is a fun little used bookstore. They have a wide variety of everything. I've been especially amused by their cookbook section. They also have I believe all the romance novels in the entire world. :)
I also enjoy the little cafe. They make a yummy Italian soda and I love that they have the all sugar coke.
The only downside really is that like the store name it's a maze. While that's kind of cute and fun it can make it difficult to find what your looking for. On the other side half the fun of a used bookstore is never knowing what you're going to find.
Also, they have board game nights every other Monday at 6pm. I've been to a couple and they are super fun. They have some games and encourage people to bring their own.
