Best we have found in many excursions anywhere so far would have to be Dumon in Bruges (Brugge), Belgium. Unfortunately, and to my deep regret, there appears to be no way to order it over the web anywhere I have found.

Another great Belgian Chocolatier is Corne Port-Royal.

I second the recommendation of Maison du Chocolat in Paris as well. Staying in a hotel nearby for a week, we stopped in almost every day for a few chocolates, and it was a great memory of our trip.

Okay, now I really have a craving.
