Review for Big M Casino - Little River Review For Mystic Lake Casino Hotel Google User Mar 30 '18 at 3:13 It's incredibly clean inside which I was surprised by. There weren't huge plumes of cigarette smoke, the floor and machines were also clean. The buffet is better than some other casinos and it has a nice variety. The slot machines could use some more variety and I wish the casino was slightly larger. Otherwise, I had a pleasurable experience. View full site to comment or like
