To me, if the chefs at Pulcinella are using canned mushrooms... whatever! They still make one of the best pizzas available in Calgary.
Pulcinella takes the bastardized North American "pizza" and tears it to pieces. Extremely palatable and simple in presentation. No pools of grease bubbling up (and eventually solidifying) on these pizzas.
I love the decor at Pulcinella... it's very polished, yet comfortable. The staff is usually friendly and helpful. Most of the appetizers I would just skip, and just go right in for the pizza. It's pricey here, but worth it for an indulgence of the traditional.
