On the days you do manage to find a seat inside the tiny and perpetually crowded West Village location of Jack's Stir Brew, turn your attention to the Happy Jack ($4.50).
Part drink, part dessert, the Happy Jack is a well-executed latte steamed with spoonfuls of fragrant honey. A generous sprinkle of cinnamon tops it off. This warming drink is just sweet enough, and bright with a triple ristretto shot. It pairs best with a few of Jack's just-baked chubby chocolate chip cookies.
