high society? but pay for her? It's little bit confusing IMHO. Narcassius was popular spot before year or more,right now it;s not so hot.But you can still try.If you wont find your desire,try "Lalunar",it's same concept.Located on Sukhumvit soi 26. Good luck !
narci is still a very good spot to pick up mid to hiso girls. though that won't be as easy as other places in bangkok. of course no money involved. when a girl fancies you in there it is either a thing of call me next days and we progress slowly from that onwards or a straight freebie!
