Glad to see someone mentioned Alterra in Milwaukee. For me a visit to Milwaukee is not complete without having coffee at Alterra, preferably at the "Alterra at the Lake" location. Specifics below. Just be prepared to stand in line on a weekend....it's a very popular place. And justifably so - it's in a great renovated building with a view of Lake Michigan! There are also five other locations.
