Drinks, Food, Table Games/Slots... Just don't play after you've had one too many.
If there is a Brewers home game during your stay (and not on our wedding day) feel free to tailgate some brats and beers and watch Americas greatest baseball franchise live.
Breakfast/Brunch joint in good ol' Stallis. SO GOOD!
Highly recommend a brewery tour while your in town! Lakefront is a solid option with tasty beers. Become the bung queen! If you know, you know.
