Just in case you didn't eat enough sweet stuff over the last few weeks, Chelsea bistro Gavroche is serving Gallete des Rois, the traditional Ephiphany cake. Starting this Sunday, full cakes cakes can be ordered for $45 (call two days in advance) while an instantly available slice will run you $8. However, if you get the piece with a figurine baked into it, you'll be be able to call yourself king or queen for the day, which might make you feel a little better about any extra holiday weight gain.
