A huge beer selection ( more than 100), and all local. That alone makes this place fantastic and worth a visit.
Awesome atmosphere. A great post-work stop off. Or a perfect place to get drunk with your friends while experimenting with weird Wisconsin brews or delicious flights. Ok I should probably stop talking about the beer.
The food is great, very Wisconsin (read: terrible for your health but amazing for your appetite). AND THE CHEESE CURDS ARE AMAZING. Seriously, best in town.
