I'm not from Chicago, I have only eaten "Chicago style" a couple of times. I'm no expert on the style but I can say this is some of the best pizza I've ever had whether it's true Chicago style or not. I got the Chicago classic (sausage, extra cheese, and butter crust) and it was spectacular. Our office is close by so I look forward to trying this place out for catering. The lunch menu was very reasonably priced and the food was delicious. The personal pizza is more than enough for one person but with pizza that good I didn't stop when I was full. I'd love to try the cookie pizza sometime, just don't know if I have the will power to save room for dessert.
Go, you'll be glad you did.
