Also, my sister asked me this weekend, "Why don't you post pictures of the cafes you're always at?"
So, the rest of this post, after the break, is for you, sister. The rest of you may look, too, if you'd like. Later, perhaps, I'll write up bits about each place. Until then, check out Alien's Day Out (a vegan in Seoul) for many and varied cafe postings. Her blog has been quite helpful in finding many places. That and this list.
