If you are into "americanized" italian food, with the garlic rolls and the overdressed salad, just stay at home. This place is the real deal when it comes to Italian food.
My wife and I had gone to Phoenix to do a project around arizona. A bulk of the work was in the phoenix area, and one of the owners of the firm had been given a gift certificate to La Fontenella. They gave it to us saying they rarely get down that way (which really wasn't that far at all) and were we glad.
The Ossobucco is brilliant, as well as the Lamb alla greca. We were so happy that we kept going back and trying new menu items.
This authentic restaurant tucked into a non-descript strip mall was one of the best Italian restaurants I have even been too in this entire country.
If you are ever in Phoenix, take the time to hit this place up.
