Don't know where you live, but I lived in Chicago basically all my life.
I thought Ginos East sucked! (And I had visited a few different Gino
franchises in the Chicagoland area over the years.)

And I also sampled thier thin crust (in St Charles, Ill), which was like
eating a Saltine Cracker with Sauce on it.
When thier pizzas take 10-15 minutes to make, from time of order, to
being on your table, something tells me, that something is already
pre-made, most likely the crust. Then they just top it, and pop it in
the oven.

If you're in Chicago, or visit Chicago, and you want the best Deep Dish
Pizza IMO, give Lou Malnati's a try. Pizzeria Uno, and Due, used to be
very good years ago (I'm talking 30 years) as they were pretty much the
originators of Chicago Deep Dish.

Nancy's in Chicago was pretty good years ago too. For Deep dish now, I
pretty much make my own, and it's very very good. Mark
