went to seoul 2 weeks ago. staying in conrad @ ifc.
had one of the most memorable sex in anma infront of manhattan hotel @ downtown seoul. cost 210k for foreigner. went there two days in a row. please ask for yuna/yoona. u wont regret it.
i also tried relay service in eve anma, pretty standard. for guys with good comm skills, try your luck in one of the bar in itaewon. managed to hook up with 2 korean gals in their 20s. when they drunk, they most likely willing to do anything
enjoy seoul safely bros.
