Delisi's Pizzeria - 784-6320. Order sausage with extra tomatoes. If you think the delivery is good, try eating it there (5806 Western Ave.) This place has been around for a long while. It recently changed ownership, but thankfully the recipe for this buttery- crusted thick Chicago-style (no sauce, just lots of tomatoes) pizza did not change. The competition is fierce, but I rank this ahead of Ginos and Lous, especially if you eat it there.
