This thread isn't helping me to resist my sweet tooth.
Green and Blacks has some really nice dark chocolates. Haven't found a German equivalent yet. Nordic (ie. Finnish, Swedish and Norwegian) are fine as well, but those tend to be more milk chocolate.
I love Barry-Callebaut/Callebaut chocolate as I used to work with it in a previous job (I used to eat about a kilo and a half each day too >_> )
