Alien Worlds has a bunch of great stuff: comic books, games, collectable toys, and more. I've been shopping there for years, and the people are very friendly. They've got a great selection of back issues, and one of the best Silver Age sections of any store in town. And if you're a fan of old toys (Transformers, GI Joe, Star Wars) you must stop by. I highly recommend this store!
Pros: helpful people, good selection, easy to find
