A friend sent me these, from Tulsa!:
Ok, technically from Broken Arrow, but I think that is pretty much the same thing. Google says they are 20 minutes apart. I don't know whether that is a lot.
Anyways, these are Oklahoma-made, Belgian-style chocolates -- apparently the family has a shop in Belgium. I could not discover the Belgian brand, despite diligent (ok, actually not-at-all diligent) online research.
The bon bons were very good. They tasted hand-made and quality. The dark chocolate discs were good as well, but I am fairly certain they were simply re-tempered Valrhona (or something similar).
Bottom Line: If you're in Tulsa (or Broken Arrow), stop by. Try to uncover the family mystery!
