How do you remember the 80's or 90's night clubs in Seoul? I think you have not been permitted to enjoy them, because you was too young. Aren't you? :)
I took a dance-sport class during undergraduate, but I forgot whether I learned salsa or not :) Anyway, there was a chance to learn salsa so I practiced it quickly and went to the real salsa club. However, it was not so good club for my taste, there maybe better salsa club... I hope so... haha.
