Florence's dining scene used to be as unchanging as the stone curls on the head of Michelangelo's David. There were humble workers' trattorias and high-end, white-linen restaurants, and that was it. Now there's a whole spectrum of wine bars (enoteche) in between. Some still focus on what's in the glass, but many offer a full sit-down meal as well. Bars that formerly sold only beverages, plus a limited range of sandwiches and panini, now lay on limited-menu lunches. Even cocktail joints have begun to offer free snacks. The best Tuscan food is simple and relies on fresh, quality ingredients prepared without rich sauces, like the famous T-bone bistecca fiorentina, from grass-fed Chianina cattle.
