The bar I liked best and was going to suggest three blocks south of Wrigley of course just closed, so that blows. The other one I like is a few blocks NW of the stadium, on Southport, called Cullen's. That's typically my go-to spot after a game. Great bar, good food. And if I want a quick bite before the game I just go to Al's, a couple blocks south on Clark. Basically my advice is to get away from the stadium before and after the game; Wrigleyville is a cesspool and you'll be fighting huge crowds for space in pretty average sports/frat bars.
