I'm always on the look out in my area Potts Point for the same reason, but not much luck lately unfortunately. Latest effort was at Heritage Thai on Victoria St, got the girl's contact and chatted her up on whatsapp but all for naught, girl prides herself on being prudish and is actively looking for a bf... have had luck with girls who know how to have a bit of fun too though - both that place and Thai village in KX.
