I suggest Santo Bevitore. On the other side of the Arno River! Before you can have an aperitif at Santino (nextdoor). Enjoy!
Hi Max, i suggest you Coco Lezzone: www.tripadvisor.it/Restaurant_Review-g187895-d696515-Reviews
Next meal at Ristorante La Maremma! Via Verdi,16/r tel 055 244615...........Handsome owner, tipical dishes, the best of Chianti and Tuscany wines...low prices.....
Well ...talking of Jappo, here is my favorite: Banki Ramen (via dei Banchi, near Santa Maria Novella Square) foursquare.com/venue/3756418 it's a family run restaurant: Japanese mom, Italian dad and strange son! :DThey mostly cook Ramen soup like this... instagr.am/p/kuac/ looooove!!
For the next time I suggest you a jappo-thai restaurrant, NIWA, close to Stazione Leopolda/Porta al Prato. It's also easy to find car parking there!
