A must-see is the Cafe Florian with its magical atmosphere. It is a luxury coffee with frescoed rooms in PiazzaSan Marco. There is nothing better in this square: impeccable service, high orchestra level, delicious and homemade food.
There is also an excellent and wide range of teas, magnificent hot chocolate. It is true that the prices are high but it is probably one of the most historic coffee in the world, in one of the most famous, beautiful and magicalsquares. Worth every penny paid.
