I've been to all of those except Cosmic Comics and Superhero comics. Actually, I went to like four different stores one day :P Me and my girlfriend had way too much time to kill and money digging a hole in my pocket.

Forbidden Planet is by far the nicest out of all the ones I've been to, but I just hate the way they have their comics on a shelf going side ways. I pull out a comic wrong and the whole thing goes down. Sooo embarrassing -_-'
