I've been to this Terroni's location a number of times in the past 2 years and my personal experience is that this place has delicious Italian food and has consistent service. Although I've seen their huge pizza dishes, they look too large for me, but I absolutely love their fresh pasta dish. Al dente, every single time. I've also tried their summer special lobster gnocchi, and their starters. There isn't anything that doesn't please.
The reason for 5 stars is the cute little patio in the back that faces right into the little park and churches on the lower part of Church street. Considering that this is downtown Toronto, this cute little view is amazing and rare. I can't think of any other downtown Toronto patios that could give a comparable view. I've recommended Terroni's for a work dinner event before, and luckily we were able to get the patio seats and I have to admit that all of the out-of-towners were very impressed with the view, the service, the food and the drinks. And I felt like the Torontonian who was "in-the-know" of all the cool places to dine in Toronto. Winner!
