If there is anyone on this forum in that area, they have yet to post anything about it. David did ask about that general area a few years ago and he had some luck with the gym I directed him to in this post.
Feel free to browse the Japan/Korea forum and certainly the rest of that Seoul thread. I believe the only places where you'll find regular BC members are the clubs near the Seoul University main campus and the one near Shinchon Station. I'm way out in the burbs and rarely make it to Seoul to play. You're welcome to play out here but it's quite a hike.
