There's some Korean spots near Station North that have soondubu jjigae -- I've heard good things about Jong Kak but I've never been myself.

I have been to Ja Kum Sung outside of the city and their Korean food is on point.

EDIT: I know you didn't ask for it, but going to shout out Brown Rice in Mt. Vernon Marketplace for their bibimbap bowls -- they're customizable akin to Chipotle.
