Shamefully, we've lived a couple of streets away from this place and had never tried it until I spotted it in the Top 10 of Ottawa restaurants. It can't be compared to the others in the list - apples and oranges - but I can't imagine a better place of it's kind in the city. As others have commented, it's the crust and the fresh ingredients. We've been sticking with the pepperoni and you can get some crazy deals on those. But the Cumberland Special is awesome too. A Greek salad was good if, as is common in North America, a little heavy on the lettuce when I'd like prefer cucumber. It's a simple pizzeria - plastic furniture, self-serve drinks from a fridge - so don't expect fine dining. Just fine food.
