"Seoul's Second Best Shop" For Red Bean, Seoul, Korea
Literally, that's the direct translation of this restaurant: Seoul's Second Best Shop (link here for directions) and they have the best red bean soup, aka "danpatjuk". The space is really small, so you'll be getting cozy with the friends you go with and others eating here too. It's not a place you'll want to sit around for hours, but rather, a place where you go in, eat, and leave; but trust me when I say this, they have great - no, amazing, danpatjuk, so it will be worth the wait and coziness.
