Review for Diamond Jo Casino Northwood Review For Diamond Jo Casino Northwood Google User May 15 '16 at 3:17 Just stopped in for the Buffet,, Prime Rib & scalloped potatoes with ham were great,, Fried Chicken had a Fish taste from frying in the same oil as Fish... Server lady was very nice and hard working, kept the soda full. Left a nice tip and plan on going back next time I am in the area. Thank You! View full site to comment or like
