Chocolate was introduced to France in Bayonne by Jewish refugees from Spain--and Bayonne still has marvelous chocolate today. It's Cazenave (under the arcades) for the absolutely most heavenly chocolate drinks. We did a blind tasting of various chocolates from the region, and Daranatz "Bitter" (70% cacao) was the big favorite. Daranatz has all manner of unusual chocolate, including one kind flavored with Espelette pepper. Henriet in Biarritz is another favorite place. There's even a Chocolate Museum in Biarritz!
