So if ever in Belgium (or Tokyo/Paris) go to Pierre Marcolinni, this is by far the most amazing chocolate, and I've samples tons throughout the years and all over Europe. He was originally a pastery chef turned choco-genious. (

PS Thanks for the info on Chocolate at the Pen, I'm going to check it out when I'm in Chi-town in a few weekends on an eating tour....
