First time here, very happy with the pizza. I have been to Chicago but have never had a deep dish, so I couldn't tell you if it was authentic or not. What I can say is that it was very good. Not too greasy, nice and filling, very tasty. Sauce tastes home made, which is a big plus. We had a groupon, which made everything free! Well, it worked. We will surely be going back to support this business with real money, asap :)
