I've never had the opportunity to try real authentic deep dish Chicago pizza (in Chicago of course), however Old Chicago's version was impressive as far as I could tell. I went in for lunch and it was slow (never a really good sign), I ordered the personal pizza/salad combo. The salad was a nice size and everything was fresh and crispy. The pizza came out hot, and the crust was soft, thick and crusty where it was supposed to be! The wait staff at this time was very thin and our waitress was over extended (she had a large table of 7 to tend to including some other tables) and ended up being waited on by the hostess in addition to who I believed to be the supervisor/manager, so service was a bit choppy. Definitely do not go to this place for atmosphere or service, but if you want good deep dish, this is as good as I've tasted thus far. I give this place 3 1/2 stars.
