There is a place called, The Fresh Market which caters to the crusty upper types that has a variety of chocolate from various places (except Brazil ... well all of Central and South America) where I have found roasted and raw nibs. Reminds one of what chocolate used to be like back in the 60s.
Just don't eat your raw chocolate with a bold Zinfandel made from old growth vines. You'll wake up in the middle of the night feeling like you ate a section of asphalt as well as tasting like hot asphalt as you breathe.
