River boat tours are a bit of a tourist trap. I guess you do see Winnipeg from a different perspective. The quality on the dinner tours was only adequate. The later tours (those that start at 10pm or so) are better for partying. (pic from Paddlewheel website)

Supper on the river cruise was terrible. The cruise was great but take the late sailing. The late one is the party boat.
