I played a couple of places in Busan. Once in Gimhae upstairs from a Vietnamese restaurant (very nice) Once in Oncheon which was very busy and friendly. Played most regularly in a  place by Hwangyeongsan. Just ask for Haeundae appt Hwangyeonsan and they will take you by taxi. Get out at the bottom of the hill up through the appartment buildings, by the two corner stores and walk through the middle of them up towards the mountain. There is a building one the right handside. The first part is a church, the second part leads down some stairs and the club is there.  Four awesome glassbacks that play really nice. Very friendly. Again 100,000 for a month (including two lessons a week) if you are serious about playing or 10,000 for a time. Not much English is spoken but they are a friendly bunch.
