One star because you had 'canned mushrooms'?? Jr T, get over yourself...
Pulcinella's one of the handful of places in Calgary that you can get something other than 'standard' North American pizza (read: not swimming in greese, glorified Pizza Hut).
'Soggy in the middle'?? Sorry... maybe this was an 'off' day but I've never seen that at Pulcinella... of course, being what it is, it's certainly not meant to be picked up in slices...
What do you get? Well besides the tasty crust and the great sauce... wood burning oven... you get real Italian cheese and meats...in a (perhaps a bit overly done) cosmopolitan setting with decent service... try the Prosciutto and fresh arugula or their spicy Diavola. (apparently you should stay way from the mushroom and artichoke... but then, who wouldn't)
Pulcinella is simply 'Best in Class' - even if I think the Napoletana certification is a bit hokey.
