My son found Diece while searching restaurants in Phoenix's Biltmore area where we enjoy frequenting when visiting the Valley of fire. We are already big fans of Ten which is located in the same complex but we were not aware it has an Italian sister! We were full of anticipation and we were not disappointed. We were ecstatic! Owner Jeff was roaming around looking more like an employee. He came over to our table to chat when I recognized him from Ten. He is always very forthcoming, friendly and interesting. We learned that his wife is Italian which was largely responsible for the birth of this sister restaurant.
According to my mother in law who was born in southern Italy and was with us, the clams they serve are the best she's ever had and believe me, she's had a lot of clams over 7 decades in both Italy and America. While I have hadn't as many, I would have to agree. They were fantastic and this appetizer would make a wonderful meal by itself.
The rest of our food was extraordinary. Freshly prepared. Beautifully plated and presented. No pretension. No fluff. Just authentic Italian fare.
I just read that Dieci closed since our visit a couple of months ago. That's very disappointing news but I am glad we got to try it at least once.
