It's always crowded, always good, and always inexpensive. The osteria is next to the church of San Niccolò, and if you sit in the lower part you'll find yourself in what was once a chapel dating from the 11th century. The subtle but dramatic background is a nice complement to the food, which is simple Tuscan at its best. The pollo con limone is tasty pieces of chicken in a lemon-scented broth. In winter, try the spezzatino di cinghiale con aromi (wild boar stew with herbs). Reservations are advised.
