We lived there for over one year - few ok kind of bars (military, tinos'). Mind you you can make the best out of any place with the right company. If you are stuck theres'always the nureybang or a short trip into suncheon. When we started there were only 5 other "foreigners" in the Gwangyang, but this rapidly increased.
shopping for food is the worst part - I advise doing a bi-weekly mission into suncheon to stock up on goddies
You didn't say where Gwangyang is in Korea. I think it is way down south on the coast near Yeosu. Oh oh. Poor Choice. The night life is pretty quiet anywhere other than Seoul. Busan is not a bad spot, and warm.
Possible heading there pretty soon. Any night life there?
thanks.
