One of our favorite "trattorie" is the Trattoria Il Pozzo in the village of Sant'Angelo in Colle where we live.
Herewith the website and address and telephone number:
Trattoria Il Pozzo
Piazza del Pozzo 2
Sant’Angelo in Colle
And we eat the "bistecca fiorentina", always accompanied, it goes without saying, by Brunello di Montalcino by Tenuta Il Poggione.
