been to the Dam a plenty of times....there is red light in several parts of the city....hottest girls are probably in the main walkway in the red light district,around 11pm..but it is waaay to public,since tourists are crowded in the area..also. look for the red light near the Heiniken Factory, and also the ones west of the central statoin.....cost wise i believe was 40-5o- euros for s*ck and f*ck....however if you want a REAL good time, i suggest goin to a sex club....for 150 euros, you get a room, champagne, and msog, mpos and the whole lot, plus waaay hotter chicks...
