Fun story : i used to live near the "moulin rouge". Every time i walked to the subway station, from which you can see the moulin rouge, i could see the face of tourists as they climbed up the stairs : first they were a bit surprised because they didn't seem to see it. Then, as they walked up a bit more i could see their face decompose as they realize that that small red stuff stuck between a giant coca cola ad and an old building was actualy the moulin rouge.
