This 17-year-old cold-weather festival is an action-packed affair that begins with this year’s holiday tree lighting in Dante Park. American Idol and Broadway star Justin Guarini and Grammy nominee Bettye LaVette are set to croon a few holiday hits before a lovely tribute to jazz singer Sharon Jones is played during the official lighting of the tree. Afterward, join amazing artists, musicians, dancers and street performers as they usher in the holiday season by juggling, walking on stilts, creating ice sculptures and performing circuslike entertainment near Time Warner Center. And if this event leaves you feeling peckish, more than 30 restaurants on the Upper West Side offer food tastings for a couple bucks. Mini Magnolia Bakery cupcakes for $2 and P.J. Clarke’s miniburgers for $4? Yes, please!
