I ate at Cibreo in Florence last week...I will note up front that I was at a business dinner with Florentine hosts...and I had a fabulous meal.
We began with a sparkling wine aperitif and numerous plates of delicious antipasti...both traditional and creative.
My three courses were all superb...
A potato and ricotta cheese sformato which was simple and sophisticated at the same time.
A unorthodox (I think) but delicious zampa di vitella dish....calves foot...basically the calves foot reduced to rich gravy with small pieces of meat that is eaten with pieces of bread--it was considered the best dish at the table by my colleagues.
A caramel panna cotta for dessert which is one of the best I have had (and I am very partial to panna cotta).
The wines were pleasant...a Bianco di Custoza from the Veneto and a young red Chianti (I have forgotten the producer).
We had several vegetarians at the table and there was no problem accommodating them.
A very memorable meal....but certainly not cheap, but not outrageous. For three courses, the total is 57 Euros without any wine. As was mentioned, much the same menu is available at the trattoria next door for a fraction of the price.
I would characterize the cooking style as "ambitious with a traditional foundation" and I am eager to return. The restaurant is well known...both to Florentines and foreigners....so it can be crowded. And Fabio Picchi is definitely a "celebrity" but he seems to always be on the premises.
