We ate there Christmas Day! Our review & pics is in the link below. Actually our review from Tutto Italia last year is in the first review link below.
I enjoyed both meal but found Il Mulino to be the better of the two. Our meal was absolutely delicious!
Click on my Oct 09 link, we had a fantastic meal there...we love Tutto but Il Mulino is soooo much better food wise, atmosphere wise and service wise.
