God for a drive around Lake Harriet, Lake Calhoun, and Lake of the Isles. Maybe check out the Minnehaha Falls. If it's nice enough, do it by bike. The city is built around outdoor biking/running activities.
If you're there on Tuesday, go out Downtown St. Paul for St Pats. Uptown and Downtown MPLS for the bars and nightlife.
See if First Ave has any good concerts while you're there.
