This is one of my favorite restaurants in the world and I always go here when I am in Florence.  I have had meals of steak, veal and pasta and they were all great.  If you love pasta try the spaghetti magnifico, it is magnificent.  The wine list is also very good.  The service is excellent.  The ambiance only adds to the experience. 

There is a cooking school associated with the restaurant that I am tempted to try.
