Review for Mystic Lake Casino Hotel Review For Mystic Lake Casino Hotel Google User Jan 19 '19 at 5:51 So fun! Cosmic Bingo is super fun. The place is really nice and clean, lots of parking, free valet, $1.00 "slot dogs" and a nice hotel and music venue. I just wish they would ban smoking inside. I would stay much longer if I didn't have to breathe second hand smoke! View full site to comment or like
