Transformer shops in South Korea (Seoul)

I know that we had a recent article on TF hunting in Japan, but does ANYONE have any hints on where to look in South Korea? Seoul is where my friend is, and he says he hasn't found many TF's in his area.
I know it's a long shot, but does anyone have any hot spots they can tell me about??
