Piazza San Marco is the touristy heart of the city, featuring attractions like the San Marco Basilika, Campanile (clock-tower), Doge´s Palace and the Cafe Florian (anyone fancy a cappuccino for 11 Euro??).
During the day, this is one of the most croweded places I have been in a long time. At night and in the early morning you more or less of the piazza for yourself, which is beautiful - I definitely promote those time of the day for a visit.
I still do not understand why people would welcome pigeons to sit on their arms, head and backs - but, you will see, many people do... argh, I am not sure how I feel about this... mostly disgusted I guess...
If you wander beyond the Piazza, you will soon find yourself lost in small side streets, mostly undiscovered and empty of tourist. It is worth the walk, believe me!
