Believe it or not, many big cities in Europe still have their own sinful side: the Red Light district.
In Brussels, Belgium, the most known place is Gare du Nord, right around the train station. But unlike in developing countries, the avenue is quite decent with an arrangement akin to shops in most shopping alley.
Along the streets, customers would find glass windows with women of many tastes, races, and ages above 18. Yes, there were older service providers, too, as customer may have an unsettled issue with his mother figure.
Many men on the street were speaking in foreign language, though.
