We have lived near Lefty's in North Park for years. My husband is from Chicago and I lived in Chicago for 3 years. We used to like Lefty's, at least as an acceptable substitute for the real thing. Recently, though, we have been disappointed with one pizza after another. We compared notes and think it has to do with the tomatoes which seem to be canned without any flavoring and devoid of their own natural flavor. Today we were at Costco, and noticed, for the first time, a bake-at-home deep dish pizza next to the standard pizzas Costco has had for years. The deep dish pizza has pepperoni, sausage and olives and was about $9.95, about half the size of a Lefty's pizza and somewhat less than half the price (if I recall correctly). We just cooked and ate the pizza and greatly prefer it to Lefty's. It is still nowhere near our memories of Chicago deep dish but the crust was actually fabulous (if not quite authentic--actually fairly buttery), the tomato sauce was good and the toppings were fine. The cheese was the only ingredient which was just average.
