My first Chicago pizza was fall of 1973 at Gino's East. Sausage, mushroom and mozzarella(for the sake of the article)cheese. It's a good thing I have never lived in that area or I would weigh something obscene by now. I was there last fall for 5 days and gained 10 pounds, 5 of which I'm still struggling with.
Gino’s sounds like my kind of place. My time around Chicago was in 89.
My aunt still makes a top flight pizza I will put up against anyone and here is a slice towards the end of dinner way back when.
