If you're looking for good pizza this is the place to go!
Service is pretty consistant: it's nice seeing the same people and that they recognize you when you enter the building. Bar-staff is always very friendly, especially the ones that have been there for a long time. Even though the bar is normally busy, most of the staff is able to handle it.
There are a lot of awesome specials and discounts at this bar. On Sundays, when I normally come in, all pints are $2.50 after 9pm. Also, you get additional food specials for having a WBT card and, with this card, you get 10% back of every dollar that is spent.
I highly recommend Old Chicago!
