There are many establishments in and around the square. The oldest and perhaps the most atmospheric is Caffè Florian, which dates back to 1720! Some of its past clientele includes Casanova, Lord Byron and Charles Dickens. It has since been refurbished and has quite an opulent style and is a fabulous place to experience. In fact, because of Piazza San Marco being such a popular place to meet up, Napoleon referred it to as Europe's drawing room.
