Not sure we’ll get to Minneapolis again as soon as I like but when we do, these suggestions from Travel + Leisure are worth trying:
Bachelor Farmer – with the city’s first rooftop garden
The American Swedish Institute’s Fika, serving open-faced sandwiches (smorgas) (which looks a bit like the cafeteria at IKEA)
Union – run by a former staffer of the famous Copenhagen restaurant Noma.

FIKA, the Cafe at ASI
“More than a museum cafe, this bright spot is a serious attempt to integrate local ingredients in dishes that are faithful to the tradition of “fika,” an institution in Sweden.” –New York Times
FIKA is the American Swedish Institute’s new Nordic-inspired café inside the Nelson Cultural Center.
