Sorry for the - may be stupid - question!
What do you mean with " real Italian food "???
Do you mean local food, for example Latio ( Roma ), Lombardia ( Milano ), Piemonte ( Torino ), Toscana ( Firenze ) etc. ?
There is no " Italian Kitchen " in Italy but local kitchen.
BTW: try the restaurant doney at the Westin Excelsior Roma
