Whats a good bar to watch a Wisconsin football game?
It kind of depends on what experience you want/where you are staying.
The bars in the 1300-1400 block of Regent (Sconnie Bar, Lucky's 1313 and Jordan's big 10) are close to the stadium and will be crowded with pregame parties that will spill over into game time and post-game as well.
Another bar that will be lively/crowded will be State Street Brats on state street.
The Great Dane downtown has a large bar area with pool tables and lots of televisions. Probably a slightly tamer crowd.
Pretty much every bar and most restaurants with bars will have TVs, and if they have a TV it is essentially 100% that it will be on the Badger game!
