Probably is the smallest wine bar in Florence, but in this case the size of the place doesn't matter, actually is pretty amazing.
I used to live a couple of blocks from this place and I swear I visited them more than ones a week. Is hard to say wish one from their menu is my favorite. I Love them all.
I highly recommend this place, you will find great flavors, amazing wines, and always a couple of great guys "I due fratellini".
