Via Tornabuoni, one of the most elegant streets in Florence, is lined with many imposing Renaissance palazzi, including a 15th-century beauty owned by the Antinori family, the famed wine producers. The ground floor of Palazzo Antinori is given over to a refined restaurant with a formal dining room—think starched linen tablecloths and waiters in white jackets—suitable for the aristocratic atmosphere. The kitchen relies on ingredients from the family’s estate, so the menu is limited, seasonal, and fresh. Not surprisingly, the wine list is deep, with a selection of super Tuscan blends and wines from the Antinori cellars.
