We had an amazing meal at a new restaurant called La Nicchia, right on LungarnomVespucci. It's only been open about six weeks, and his helmet by Florentine chef who trained and worked in Switzerland for several years before returning home. We had an exquisite Risotto in a Parmesan shell; antipasto for about 8: homemade pasta that might be the best I ever had, and the chef special dessert ,an assortment of three mini desserts that she creates each day. We got a lot of help with our wine selections as well as a Vin Santo that was exquisite. Total for two €75 and well worth it.

They also have a daily lunch special for 10-year-old that looks great.
They're only on Facebook. No menu available but worth checking out.
