Hanging around Florence and Sienna involves many things - most of them good. There's the best pasta you've ever eaten, Bistecca Fiorentino, Chianti Classico, 482(ish) Madonnas with Child at the Uffizi, Vespa tours, and Aperol Spritzes at the Piazza del Campo. If you are really brave, you can also try Lampredotto.
Just remember, no cappuccinos after 11a.m.
