Café Nazionale is close to the centre of Quarrata on the main road in from Prato. It's a busy place, very popular with locals. The ladies running it are charming, producing great coffee quickly and with skill. There are chairs outside, but a lot of customers take their coffee inside, so there was room for us as we passed on our early morning rides. I have reviewed another café in Quarrata elsewhere on Trip Advisor and it's difficult to choose between the two, so my recommendation is to try both.
