da Rocco
At one of Florence's biggest markets, you can grab lunch to go, or you can cram into one of the booths and pour from the straw-cloaked flask (wine here is da consumo, which means they charge you for how much you drink). Food is abundant and Tuscan, service is fast, and locals pack in. The ample menu changes daily (nine secondi are the norm), and the prices are great. On Friday, fish is served.
