We have been to the other Grazie location in Vaughan as well, but prefer the Yonge St location best. The pizzas and pastas are excellent, however I would not say they compare to authentic Italian restaurants.
Salads are mediocre.
The atmosphere is nice, there seems to be long line-ups on weekends for dinner. This is our restaurant of choice, but only if we are in the area.
We had the Nico pasta a couple of nights ago and this has to be the best pasta dish we have had here.
