Review for Terrible's Lakeside Casino Review For Terrible's Lakeside Casino Google User Jul 10 '18 at 0:33 I have never had an issue with Lakeside Hotel Casino in Osceola, IA. They have EXCELLENT customer service. Every employee encounter was pleasant, polite, and helpful. I attended a concert, played slots, and stayed overnight. Rooms were clean and comfortable. Would definitely recommend! View full site to comment or like
