Harvard Square (Cambridge, MA) has a hot chocolate cafe just as you describe. Sinfully rich.

There's a chain of stores called Moonstruck Chocolate that specializes in this - it bills itself as a "Chocolate Cafe". They produce a wide variety of chocolate drinks, with coffee/espresso and without.

Someone should bottle the stuff, as Starbucks does with its Frappuccino. No one seems to be marketing a good chocolate drink for adults. Yoo-hoo is simply awful, and doesn't even taste as good as plain chocolate milk. No wonder they focus on the children's market. What I want is a rich, decadent, and caffeinated chocolate drink. This seems to be yet another open niche in the beverage market.

Does anyone here have any contacts in the industry?

I believe Barry is referring to Burdick's. Their white hot chocolate is so good, it ought to be illegal!

It's about time there were some variety in this market. Aside from generic, there is swiss miss, and that is about it.

Caffeinated? There is caffeine in every cocoa bean already, just like coffee. As for decaffeinating chocolate, that is not something I would even want to consider. Chocolate is not a children's drink anyway; after all it was first drunk by Maya kings out of gold cups. As for Curious Cat's reference to 'the industry', in this case I think that would constitute anyone who runs a diner or deli. So if that describes you, be creative.
