I consider Sourdough the best pizza joints on the East Side. The crust is moderately thin and crispy, but not dry. The toppings are very fresh and flavorful. The sausage is seasoned well, sometimes crumbly, never rubbery. Order the Titus...it's been our favorite for at least 5 years. Not that we're stuck in a rut or anything.
If you eat in, expect a pleasantly basic place in a sleeply strip mall. We don't mind it there, but usually do take-out.
