I opened my last ChocolArts bar at work today.
Yum, this bar was very good. The dark chocolate was very rich (probably around 55%, but darker would have been nice), and the hazelnuts were whole and roasted and crunchy and very tasty. I think this was my favorite bar of all of them, and I liked it better than the cashew, coffee or cacao nibs bars. And given that the entire bar was gone in four minutes, I think my co-workers liked this one too.
