I've been back to Old Chicago, and I think they deserve an upgrade. The service is steadily good, there's always new beer to try, and the prices are reasonable. I had a pizza there with a friend and we were both pleasantly surprised at how good it was. It was a "Chicago Style" - which, by the way, is emphatically not a Chicago-style pizza - with pepperoni and green peppers. The crust was buttery and bready like a good pan pizza should be, with great cheese and the just-right amount of pepperoni. I thought they could have gone heavier on the green pepper, but I'm just nitpicking.
Service was attentive, friendly, prompt and timely. I'm starting to hang out there a bit with friends as it beats quite a few other neighborhood places out in price and quality while also having more pleasant surroundings and room to move without tripping on your neighbor as at some other area watering holes.
