These days, when you're in Mexico, hot chocolate is usually, sadly, made with powdered Nestlé crap. The crumbling of pure dark-chocolate bits into a slow melt-and-simmer dance with milk or water is quickly becoming a thing of the past. But not at Viento y Agua (Wind and Air), where the coffee shop's purveyors have taken the old Mexican tradition to new heights with their Mexican Mocha, a sumptuous blend of crumbly Ibarra chocolate (okay, kind of mainstream for Mexican hard chocolate, but better than Nestlé), espresso, a pinch of cinnamon, and a thick, multiple-spoon-dip layer of foam. Take it slow—you won't regret it.
