If you are into science fiction books at all, this is the place to go. They've got lots of new and used books: ones you recognized and others that are more obscure. They will sometimes also have hard to find books, and you'll get far better trade on sci fi books than you will at other conventional used book stores. In addition, the staff are great at recommending books based on what you've enjoyed in the past. This place is always on my dad's must visit list when he is in town!
