I registered on a few Korean sites and got access to info on Korean-only places. Google-translate is pretty crappy, but you can see some thngs on specials (called "events") and the girls (very HOT). These K-guys have a lot of high quality talent available to them. Sometimes for as little as 60K for 60 minutes before 2pm. Typical is 60 min for 90K. 90 and 120 min also avail. The reg process is not hard to figure out but keep Bing Translator open in a sep window because you need a Hangul-only name, so translate the one you want (no spaces). These are three I registered on.

Most copy is jpeg so it doesn't translate but you can figure out pricing info (minutes and # of KRW). And the pics are great. I think most of the places are "office-tels", which are apartments where the girls meet you. Its supposed to simulate going over to your GF's place. Phone numbers are there so have a Korean call and see how it goes
