An extremely fun activity in Turin is to have a cup of Bicerin, a local drink made of chocolate, coffee, and milk/cream, invented by the historic Caffe al Bicerin (established in 1763).

It is served in cafes all across the city, but I think you should also try the original one. While the prices may be a bit steep, I feel like it's worth a visit to savor this iconic beverage in its historic setting.
