It is the restaurant that most workers in the area go to when they want to eat something really good during their lunchtime. What is nice about it is that they have a beautiful terrace in the front of the restaurant where you can chill even if you don't want to eat.
Visiting here would be the wrong word, but going to eat something typical from Belgium there is actually a good idea if you are around the Cinquantenaire and have no idea of where you should go eat.
