Ancient Aperitivo Tradition: while in the Mercato nel Quadrilatero area, stop by Osteria del Sole, the oldest osteria in the city! It was opened in 1465, and still to this day, it is one of the most famous spots in the city. The Osteria serves only drinks (mostly local wines), but they allow you (and even encourage you!) to bring your own food. So you can buy something at the market and eat it in the Osteria del Sole while sipping on one of their renowned wines!
