I have only been to the Johnny Carinos in Grand Prairie. They have good bread and a garlicky olive oil dipping sauce that is pretty good.
The food was good, but nothing to write home about. My husband usually has the veal or chicken parmigiana, and I have some spicy chicken pasta. Pluse we have always had spotty service there. I think they hire too many kids who just don't care.
If you are looking for an out of this world Italian experience, try Carabbas. From the bread to the soup to the Chicken Marsala, everything is to die for!
