The most famous café in Siena, opened in the 1880s and still owned by the Nannini family. The pasticceria sells some of the best ricciarelli and panforte in the city, and the bar is a reliable place for an espresso among Sienese commuters rather than tourists.
Stand at the counter and order an espresso and a ricciarello (almond paste biscuit) for the classic Sienese mid-morning pause.
