Valeria,
I am not Italian but I have a serious love of Italian food and CT is blessed to have a number of authentic Italian restaurants.
The owner/chiefs of the following restaurants are all from Italy:
L’Orcio - 806 State Street, New Haven, CT

La Scogliera - 697 Madison Avenue Bridgeport, CT
Tuscany Ristorante - 1084 Madison Ave Bridgeport, CT
Roseland Apizza - 350 Hawthorne Ave Derby, CT
I think the owners of La Scogliera and Roseland came to CT as children so I don't know if they still speak Italian fluently but the gentleman at the other two restaurants came here as adults and are fluent.
