Mall of America, Bloomington

The largest shopping mall in the United States, with more than 500 shops and 50 restaurants on four levels. In the middle is Nickelodeon Universe, an indoor theme park with roller coasters, plus SEA LIFE Minnesota Aquarium, mini-golf, an escape room and a cinema. Minnesota has no sales tax on clothing and shoes.

Weekends are very crowded, so visit midweek if you can. The METRO Blue Line light rail runs to the mall from downtown Minneapolis and from Minneapolis–Saint Paul Airport, which is only a few minutes away, so it's easy to visit on a layover.
