If you're a home cook, it's possible to make a very passable Chicago style pizza at home. I've done knock-offs of Giordanos's stuffed spinach and also a standard Lou Malnoti's.
But I'll admit that it's a bit tricky if you don't have that base knowledge of what you're going for.
I think this was the resource I used to back-engineer the crusts. The rest is getting the order of ingredients (cheese on bottom to form a fat shield that protects the crust, toppings, potentially more cheese or another razor thin crust, then red sauce.)
That looks like a perfect copycat Giordanos! I used to make those at home before they opened one up locally in ~~American hell~~ Ohio.
They make my friends in Italy SO ANGRY. They insist that it's some sort of quiche or casserole. And then I point out that I've been to Italy and seen the hotdog and french fry pizza with my own eyes. That makes them angrier.
