There are three RLDs in Amsterdam – the main one (de Wallen) – basically a tourist trap these days as Jaydefo has explained. The other two, smaller, RLDs are used more by locals. One is on the Singel (centred on Spuistraat and Oude Nieuwstraat) – better service probably, women tend to be older, milf -types; the third RLD is further south near Ruysdaelkade.
