I'm always intimidated when I go into hard core comic book stores, because the extent of my comic knowledge stems from the Archie Comics I read growing up, and I don't think they're decidedly "cool" in the comic world.
However, this store is slightly different because it carries art books too, some of which I happen to know a fair bit about. And so, my confidence returns and I feel comfortable that no one is going to challenge me to a spontaneous comic book final Jeopardy round.
