I parked at Cobblestone's once and it was a pretty good deal. Used the credit for their muffaletta sandwich and it was a boss.
I also spent a couple of nights at Catchers back in the day. It seemed like the quintessential Chicago corner bar. But I think they had increased patronage from some shady characters their last couple of years that scared away their regular business. At least from what I was told.
On the flip side, both Cork and Turtles seem to be slammed before every game. Nice to see that (unless you are looking for a seat at the bar).
