Review for Argosy Casino - Sioux City Review For Argosy Casino - Sioux City Google User Jun 17 '18 at 14:55 Worst hotel experience I've had in my 34 years here. First room toilet leaked. No biggie we get another room. Go out for the night and when we come back we flush this toilet and water sprays all over everything we had in there. They put us in a 3rd room and this toilet runs all night. 3 rooms 3 non-functioning toilets. Paint peeling all over the bathroom, mirror had weird black mark's all over it. Wont be staying here again. View full site to comment or like
