My parents were in Europe and did right by me:
The Xocolat-brand "Cats' Tongues" were delicious. They were very chocolatey -- almost definitely entirely West African. Nothing fancy. Almost candy-esque. But real 70% chocolate. I approve.
The Marcus Schurer 72% bar was a bit more adult. It had some earthy tones to it, which I enjoyed. I don't know why, but I had a mild preference for the cats' tongues. But both were great.
Bottom Line: I may need to investigate the German chocolate scene -- clearly they are doing something right.
