Since moving from Marda Loop to Okotoks I sometimes consider moving back just for the pizza selection.
My picks for that area:
1) Volos
2) Sophie's
3) Greco's
4) Spiro's
Okotoks pizza SUCKS. I've tried them all in town, and they're all terrible. The closest to decent is Pizzaberg, but it still tastes like cheap cheese and cardboard.
