Wrigley Field is locked into Anheuser Busch, so the best you can hope for is some Goose Island beers. I've seen reports of Matilda on tap, but haven't seen it. The Chicago beer scene is booming, so it's too bad they can't find some space to highlight the locals. US Cellular is supposed to have better choices, but that would mean you were at a White Sox game
I haven't been to Mobile Phone Park in ages. We used to go to Comisky all the time as a kid. I would love to see Chris Sale pitch though. Yeah, I haven't been impressed with Wrigley's offerings. Owing to the inconvenience of getting to Wrigley, I have preferred to see the Cubs in Milwaukee. We are going to see them in Cinci this year, which I am looking forward to.
We went to Kaufmann Stadium in Kansas City a couple of weeks ago, and sat in the "craft and draft" section. Lots of good options there, and the food was quite good as well.
