The last time I was in Brussels I got really surprised for seeing so many people in the streets.
I was passing by the crossing close to the metro station of Porte Namur around 22h and you would usually see one or two people around and some cars passing by.
Although it was a cold wintery night there was so many people as it was 17h in the afternoon... Well, almost as. It was so good to see some live out in the streets.
