Old Chicago is a good restaurant. My rating is based on the quality of food and overall experience I had there. It is important to note, however, that Old Chicago does not serve Chicago-style deep dish pizza as the menu claims. It is good but it simply is not Chicago-style deep dish. For a true Chicago-style pizza, try Oregano's. I'm giving Old Chicago 3 starts because I think the "Chicago-style" description is deceptive.
That said I was impressed with all the food ordered. My friend loved her "Chicago-style" Thai pie pizza. I had the Meat Me calzone and it was fantastic. The crust was delicious and the calzone was stuffed with a variety of meats and cheese. Even the dipping sauce on the side was good.
The beer selection was the largest I've seen in the Phoenix area and they have some great offerings from local to foreign brew. If you've found a pub with a greater selection you may not find your favorite here but the expansive drink list will leave most browsing for awhile.
Service was slow at times between each stop by the table but overall they did a very good job. The lengthy gaps left us sitting longer than we needed to but they had a lot of televisions to keep us occupied so it wasn't too bad.
Old Chicago looks like a good place to catch a game and have some drinks. I will return for another Meat Me calzone at some point in time.
