The bar was beautifully tempered, shiny and smooth with lovely raised sections. The chocolate is dark, containing no milk, and has a very firm bite. It's melting point is a little higher than I like, making it feel just slightly waxy, but the flavor was well rounded with a hint of tropical fruit — namely banana. The toffee gives a bit of texture to the bar, but not much. In fact, I felt there wasn't quite enough toffee. There was, however, plenty of salt, which was liberally sprinkled on the back of the bar. On most of the pieces, the overwhelming flavor was that of salt.
Overall this was a good bar. I ate the entire thing over the course of a couple weeks, having only one section at a time (because it was so darn salty). If there was a bit more toffee and a bit less salt, I think this would be an excellent chocolate bar.
It looks like B.T. McElrath also makes a Prairie Dog Bar which adds almonds and uses milk chocolate instead of dark — I'd like to try that one as well as their truffles someday. You can see more at their website.
