Once a traditional mom-and-pop neighborhood deli, Zeb is now a hip lunch spot in the charming San Niccolò area south of the Arno. Mom Giuseppina is still in the kitchen and her son, Alberto, looks after the guests who perch on tall stools around a U-shaped bar, from which you can see the dishes on offer that day. Giuseppina's homemade pasta is fabulous—the choice varies daily and with the seasons; think pear and ricotta ravioli served in a puddle of melted butter, fresh tagliolini with truffle shavings, and pasta with porcini mushrooms. Other typical dishes include superb melanzane alla parmigiana (eggplant Parmesan), bread-and-bean-based ribollita and bollito, a local specialty of mixed boiled meats served with pungent salsa verde. There's a wide choice of vegetable sides, mouth-watering homemade desserts, and a good wine list. This is an ideal spot for a quick lunch; if you want to linger, go for dinner (Thursday through Saturday).
