Aside from parking, I don't think I or my family ever spent a dollar in that area outside of the ballpark. I went to that on-site bar they opened once. I knew of nothing to do there, you get off the highway, follow the signs, park, give Reinsdorf the parking fee, then leave. You eat somewhere else and you don't spend time there afterwards, or beforehand unless you bring stuff with to tailgate. Our normal setup growing up was to stop at the McDonalds at the Skyway oasis for dinner and met dad there coming out of the city.
When I lived in Pittsburgh, I took the bus in, had dinner before every game, took photos on the bridge, usually stopped at the bar across the street, might have stopped at a bar or shop on the way home. Spent probably $100 more every time and was happy to do so.
