(I live in the Twin Cities, so MSP is my airport.) The linked article only mentions Concourse G. Most of the local-style restaurants I can think of off the top of my head (e.g. Surdyk's, Angel Food) are in the main hall or Concourse C area. So I guess OTG probably does some of that, but does not own all of the "local" restaurants in the airport. In fact, the presence of the other local restaurants may have encouraged OTG to contract with local restaurants to fit in and seem more local. Just spitballing.
