The Mayan hot chocolate at SOMA is the best spicy hot chocolate in the city, hands down. It's closer in texture to molten chocolate than to the more common chocolatey milk. When I got a gig near the SOMA on King St, I knew I was bound to overindulge. And I did. I once bought the mix and was shocked at the number of calories per cup. I was also disappointed that I couldn't quite make the mix fully dissolve. I guess you need the special machine.
