In Sorrento there is a well known gelateria called Bar Primavera. Every Christmas they make a Nativity Scene, known in italian as a presepe. This years presepe took a month to make and was made with 450 KILOS of chocolate!
The scent of chocolate is so strong that you can sell it already as you walk through the main square. If you happen to be in Sorrento this Christmas be sure to visit Bar Primavera and admire the presepe, while maybe trying one of their hot ice-creams!
