Milwaukee, WI area

I went to a restaurant near Milwaukee a few weeks ago. I was treating, and I wanted to bring a bottle of Hundred Acre. I am not from WI, and the person at the restaurant told me it’s illegal for people to bring their own wines to restaurants in the entire state. That sounds a bit hard to believe, so I was wondering if anone knows for sure. Thanks.

Yes, it’s against the law, PM me for deets.
