/ Florence, starting point for Dan Brown's new book, Inferno, is always listed in the world's top-ten places to visit because of the Renaissance tradition we still see in the architecture, and the overall beauty of the city, not to mention great restaurants. Our walking tour with local guide brings us to the Duomo, Piazza della Signoria and across the Arno River to Oltrarno. We also enjoy steak at il Porcospino, a favorite restaurant, with a most friendly waiter, Franco. Part 3 of our recent video tour of Europe.
