The general area is known as Schipperskwartier which has recently been 'developed' or 'tamed'. The area of interest still is between St-Paulusstraat and Brouwersvliet, including Verversrui, Vingerlingstraat and Schippersstraat. The Villa Tinto is a major establishment in the area - more information on this link

The trade has recently been officially prohibited in Charleroi except for the establishments on faubourg de Bruxelles and the N5, both in Gosselie, to the north of the town
The trade formerly centered on 'Le triangle de Charleroi' bounded by the rue Moulin, rue Desandrouin and rue Fenderie, but was officially forced to move by the council to the area around the ministère des Finances: rue des Rivages, rue Monnet, la place des Tramways and the beginning of rue du Grand Central, up to the junction with the rue des Rivages. Seemingly, the trade in the Triangle kept returning and the 'new' areas were less secure. Whether the trade still exists in these areas, irrespective of the new regulations, I do not know at the moment.
Kortrijksesteenweg (N43) on road which leads to Sint-Martens-Latem
Two streets near to each other :-
Pieter Vanderdoncktdoorgang (300 meters north of Gent Zuid railway station (and City Shoppingcentre Gent Zuid), also referred to as glazen straatje presumably because of its arcade nature (see picture).
Belgradostraat, a hundred meters or so further North.
The situation is in a bit of flux at the moment, I believe - follow this link for further information
Confused about the current situation - have various addresses but unsure about their current validity. Addresses include Langestraat (north of the ferry port), Hazegras (adjacent to the railway station), Fregatstraat, Vrijhavenstraat, Oesterbankstraat.
Windows along Luikersteenweg (the N3 road between Sint-Truiden and Liège), known as "Chaussee d'Amour", colloquially, apparently).
Stories tell of traffic being regularly held up because of this 'distraction' and of a higher-than-expected accident rate along this route.
