On a related note, I ran into this on the New York Times today (free registration may be necessary).
Summarizing: A number of small companies are trying to make inroads into the restaurant chocolate business in New York, eventually unseating Valrhona, the present gold standard. A new outfit from San Francisco is selling chocolate under the name of Tcho and is learning just how difficult it is to break into this traditional market. I was surprised to learn that one of the owners of this new company was Jane Metcalfe, a founder of Wired magazine. I also found interesting the fact that the owners say they are working with cocoa farmers to improve their crops and products, just like some coffee importers are doing.
