Well, the original is Pizzaria Uno, on the near north side, but chain locations all over the place, heck, I was at one in Dayton, OH
a year ago! There is one AT ORD
, but the original is at 29 E Ohio in Chicago. www.pizzariauno.com for locations and phone #'s
Personally, I think the best deep dish is Gino's East. Pan, w/ crumbled sausage. Again, original is on the near north side, but franchises all over the city and 'burbs. Original is at 633N. Wells, closest to ORD
would be the Rosemont location though. website is www.ginoseast.com
Giordanos is, I think a close second behind Ginos and Uno. Though, after spending 2 summers in Jersey, where all they have is New York style "pizza" I have to agree with Superfly, there is NO comparison.
Chicago style pizza is a MEAL; one piece and you're full, two and you're stuffed. Don't know about 3; I've never been able to eat more than 2!
