Review for Mystic Lake Casino Hotel Review For Mystic Lake Casino Hotel Google User Nov 11 '16 at 12:58 Largest and best casino in Minnesota. Amazing buffet with a great selection of food. The casino gets fairy smoky, especially on busy days. Cosmic bingo is fun, however I had nowhere to sit after purchasing my cards. They have a large number of tables "closed" and refused to open them or allow me to sit when I asked where I should sit. I asked if I should just stand then and they said that standing was prohibited. People kept flooding in and began sitting at the "closed" tables so I joined them. Almost missed the first game.
