The Piazza is a very romantic place, and the perfect place to "meet" people. I am there almost every night for walking, talking, and listening to music.
Enrico and I have become relatively good friends. He works at a restaurant near Orsan Michele Church and between Piazza della Republica and Piazza della Signoria. He works 6 days a week, for 10 hours a day. Enrico is from Sienna, which is a small town about 1 hour train ride from Florence.
When you come to Florence, I will introduce you to Enrico. He is a big hit with the young American girls and makes most of his money in tips, even though you really don’t tip in Italy, and especially where he works, which is a "self-service" restaurant.
Enrico and I meet occasionally for coffee or to walk. Here is a photo of us in front of the replica of David on the "pick up piazza".
