Unlike many other major US cities, taxis are both expensive in Minneapolis and somewhat more difficult to find.  In downtown Minneapolis and St. Paul, the best places to find available cabs are at hotels.  Also, telephoning a cab company will work.  Minneapolis and St. Paul are unlike New York City for example; you cannot expect to stand on a downtown steet corner and hail a passing cab.

Cab rates are set by local ordinance so one should not be concerned about the validity of a cab fare.  It is worth noting that fares leaving from the Minneapolis-St. Paul International airport include an additional special airport fee-under $5.
