My favorite hot chocolate is from Schakolad, a chocolate shop in Plano, TX. They mix hot milk with the warm chocolate they are using for chocolate molds/novelty gifts. You can get it with dark or milk chocolate. The owner told me that each type of chocolate needs to be at a different temperature to keep it flowing. Schakolad is a franchise...don't know if they make the hot chocolate in all locations.

I discovered this place because it was listed as an IDINE location and I could get FF miles as well.
