At long last, I made my journey to pizza mecca (as was reputed) and can happily say that I wasn't disappointed. We were able to jump over the wait line because we were with someone who was on the "in", so I think I evaded the annoying bit that way.
The appetizers were definitely stand-outs of the meal - beef carpaccio, mozza and tomatoes, tasty slices of bread with fragrant olive oil - all excellent. Needless to say, the pizzas were not to be missed either. It is expected that some comparisons will be drawn between Libretto and Terroni, and I must say that where Terroni fails, Libretto succeeds. Not a burnt/overly crispy crust to be seen - anywhere! Delicious ingredients and topping combinations, and yummy soft, doughy thin-crust pizza.
It is irritating that the place is as noisy and busy as it is, but I guess that comes with the territory when you are up there as one of the reigning champions of pizza in Toronto.
