Imagine yourself sitting on the terrace of the 14th-century Palazzo Capponi delle Rovinate, watching the sleepy crawl of the Arno as you savor a plate of hand-cut french fries and a big, juicy gourmet burger cooked to a pitch-perfect medium rare. Welcome to Lungarno 23 (dinner for two $70), Florence’s newest must-hit café, where there’s nary a porcino or pappardella in sight. Dedicated to the fine art of preparing Tuscan-style meat, the trattoria is run by the owners of Tenuta La Fratta, just outside Sinalunga—one of the last farms in Tuscany’s Val di Chiana to raise pure Chianina cattle. Order up your choice of a 100 percent organic burger, a roast-beef sandwich, or tartare. And don’t forget a glass of one of the many reds on offer from the likes of Biondi-Santi, Frescobaldi, and Antinori.
