I got taken out here during one of my first weeks back in Canada. The service was friendly (although slow due to the sheer amount of people) and they certainly were trying very hard.
I was little unimpressed by the prices of alcohol. Some glasses of wine cost the same as an order of pizza. The pizza itself was good. The crust was fresh and wonderfully made. The center was oddly soft, but I can't tell if that was the restaurant's style or it was slightly undercooked (didn't seem so). The toppings were to die for, so the crust wasn't a big deal.
Honestly, the pizza at Pizzeria Libretto really reminded me of the handmade pizza I ate in Korea. And while Korea's pizza usually hits the spot, it's not exactly the country for pizza. Libretto is a wonderful place, but the pricing is what holds me back. I'm still gonna give it 4 stars because I believe the atmosphere and quality of ingredients and service is worth it.
