La Maison des Chocolatiers – If I died in Brussels inside this place I would be just fine. Bury me right there amongst the divine sumptuous chocolate treats. La Maison is one shop shopping; ten different 100% Belgian chocolatiers sell their brands. The sales staff are very knowledgable on the history of chocolate and the differences between Belgian chocolate and other countries distinct uses of cocoa. You can sample anything in the cases and they sell gift boxes from each brand.
Ask them about taking a tour where you can learn the history of chocolate in the area and see how it’s made.
