Restaurants on well-known piazzas are not usually supposed to be good-- but this one bordered on great. Main dish was a treat, visually and verbally-- thin slices of tender beef topped with rucola (rocket salad) and shaved Parmesan cheese. Wine by the glass was spot on, service exceptional. As a breeze filled the outdoor restaurant, waiters passed out blankets. Incredible! Circus Ristorante is not to be missed in Florence.
