When I have been in Seoul, never needed any assistance... Found girls almost lining up as I play tourist and try to find places to go. One super hottie tried to make me Christian... that didn't work
Aside from that, just sitting down with coffee on the water plaza was a treat, many girls going by and some single girls or two friends often sit down and chat with me. Of course best demographic is the one that learnt English, 16-25 female.
Almost as good as Japan... ok, it is as good as Japan.
Lots of fun, many great memories, want to go back each day.
