On Sunday, December 21st, Met Back Bay will feel like a winter wonderland as it transforms itself for a Storybook Christmas. From 3:00-6:00pm, kids of all ages are invited to cuddle up with a cup of hot chocolate, snack on freshly roasted chestnuts and listen to Victorian Carolers singing Christmas songs everyone knows (and loves). Santa will be there at 4:00pm to take photos and read The Night Before Christmas by the fireplace. You don’t need to buy tickets but reservations are highly recommended. Call 617.267.0451 for yours asap.
