We enjoyed this restaurant very very much!
It's located a bit outside the touristic zone but is certainly a top restaurant in Florence.
I would highly recommend to book in advance.
They served tasting menu, where you we could try several dishes in small portions.
You can choose to have 3 or 4.
Sure enough to eat ;)
They also have a great winelist and the Spumante was delicious.
The atmosphere is quite modern, but intimate. We enjoyed our little table next to the bar.
