City Bakery's annual Hot Chocolate Festival is one of the few warm patches of frigid New York Februaries. A range of daily flavors --- spicy cinnamon, say, or Arabian Nights --- join the gooey original blend to ensure that New Yorkers get the necessary sugar and calories to battle the cold. In an effort to go green this year, they replace the lights with candles in the upstairs seating area every day at 3pm. It's not quite as romantic as it sounds, since the lights are still on in the main cafe area below, making the upstairs more candle-inflected than candlelit. But taking a quick break in the middle of the day to drink chocolate with homemade marshmallows is not the kind of thing even a New Yorker can complain about.
