You totally forgot to mention one of the most outstanding chocolate shops in the US and certainly in Texas, Chocolat du Monde in Houston, TX. It is located in the Rice Village area at 5302 Morningside & the link is http://www.chocolat-du-monde.com/

They have been providing the world's finest chocolate to the Houston market for many years. They ship worldwide (dry ice works wonders). I found them while living in Houston, but also found that many of their gourmet chocolates were unavailable in others parts of the country I was living in at the time. The owner, David, is fabulous, knowledgeable about his product and very helpful! Until you have tried really great European chocolates, you have not tasted chocolate and once you do, you will never want the mediocre stuff again!
