Dish Pizza

Where can I find a family restaurant with authentic Chicago deep dish pizza style in St. Louis, MO?
I've been craving pizza style Chicago for a while, and wondered if anyone knew where I can find authentic Chicago style pizza. I'm talking about pizzas that weigh about 6 pounds, and are about 5 inches high, with the sauce. This has to be a family restaurant, or one where you can take the kids.
