For the best chocolate around the Grand Place go to Galler,in the little pedestrian street going down towards Bourse. My favorite is the Noir 85
This bar is THE Eldorado : thousands of beers from Belgium and all over the world. But be careful, it's a VERY busy place; tourists (and a few locals) invade it day and night.
