I being italian, and my parents being traditionalist from the old country who very rarely go out to restaurants, they've been known to occasionally go to Zafferano's. It's on Weston, just south of Langstaff (I believe. It might be just north of Langstaff. lol) It's on the east side of Weston in the same plaza as a Quizno's.
I've been there several times myself and it's very authentic.
