Grazie is one of my favourite Italian restaurants. It's good quality, fresh ingredients and reasonbly priced. They have a ton of different pastas on the menu - i've tried about 5 diff ones now and liked them all - I'm never disappointed when I eat there. My favs include the branca salad, penza and tasca pasta.
I hear the location at Yonge & Eg always has a line-up - the Vaughan location is the same menu and i have never had to wait!
