For.... Science!
I took lots of pictures for you, so you can share the experience.
I went with the Salted Dark. It's 70% cocoa. The salt seems out of place at first, but then somehow brings out the fruity note of the chocolate. Like a lot of the really dark chocolates, it finishes very clean, without feeling like my mouth is candy-coated. It's a little strong to be a bar that I would just sit down and eat. I'd probably have a half a piece after lunch, or as a special treat.
Bottom line is that it's ok. I've had better. I am curious about some of the other flavors that they have. I might try a different one as a splurge sometime.
