Sammy's consistently delivers quality pizza in a timely fashion, and honestly, consistency in Calgary is key. They make a great pizza. The crust always has that light buttery consistency, the toppings are always fresh, and the sauce has a tanginess that is somewhere between sweet and tart--making a great pizza when put in combination.
I've only ever tried their vegetarian, and I have to say that 9/10 I don't appreciate large pieces of tomato added to the top of my pizza. It's weird to me. I want things contained by cheese. Call me OCD, but it's just how I feel. In the case of Sammy's, however, the tomato seems to blend with everything else. Well done. It's actually pretty impressive.
