HQ Gwangan
Appropriately named, this rollicking Western bar is indeed the headquarters for expat nightlife in Busan, though it also attracts a significant Korean clientele. With quality drinks, live music, amazingly good pub grub, and a million-dollar view of the Gwangan Diamond Bridge, HQ is always a hoot. It's also the best place in town to watch sports, and the staff and owners are as friendly as it gets.
