Agree with all of this, the downtown area is pretty solid with plenty of options, but it's not the most conveniently located in relation to pre and post game activities. I live 5 minutes from the Denny and there isn't the greatest selection in that area of town yet, but there's a Buffalo Wild Wings basically in the parking lot of the arena, if that's your type of fine dining. Across Russell Street attached to the new Holiday Inn there is the Crooked Pint Ale House. There is also a Mexican restaurant, Casa Del Rey across West Street on the east side of the arena which is a great place.
As a lifelong North Dakotan, and UND grad, currently living in Sioux Falls I was pretty disappointed we couldn't make the regional, but I still look forward to watching some good hockey this weekend. Hoping some UND fans still plan on making the trip and providing a good atmosphere.
