I have visited the above places to hunt girl while i was on business trip last month.
First, location is easily to be found, by referring guideline set out by another bro in his thread....
However, quality of girls is quite disappointed...i did walk around several times to look for an "appropriate" girl to fuxk.....even some of them are fatty pork chop and oldies....so disappointed to this area...
I came to Seoul in mid-June and will be checking out soon. I have been to this place three times by using the subway system like the way other C-Hing suggested. Generally speaking, the girls are OK, however, some of them do not like Chinese. In these three times, one girl thought I am Japanese; the other two, thought I am overseas Korean. I just spoke English to them. The thing I don't like is no shower, they just use wet towel to clean my jj before and after. Horrible, so many people using the same bed! Anyway, they are tall, good skin, heavy make-up; but very polite. Even they didn't want your business because you are Chinese, they just shake their heads and smile. I like the tatoo girl I had last night. I am going back tonight after chicken jinshen soup - good for your body!!!
