Wilson's Bar is one of my favorites for sports. Anything Wisconsin affiliated will bring in crowds of regulars and new patrons alike. Televisions are plenty, some tables even have their own ~25 inch TV mounted on the wall above the table - extra bonus!
The tap and bottle lists are fairly extensive with lots of Wisconsin microbrews to offer. Wilson's offer standard burgers and sandwiches with some nightly specials. The free popcorn in the back corner is addicting - and it's not oversalted like so many other places.
Pro tip: if you're going to watch a highly anticipated Wisconsin sporting event, get there early! Seats/tables are limited, and the place fills up incredibly fast.
