Review for Argosy Casino - Sioux City Review For Argosy Casino - Sioux City Google User Jul 23 '17 at 4:51 Cockroaches!! pics are NOT up to date. Pool looks to be 20 years older than the pictures. Cockroaches... Did I mention, cockroaches? Exposed electrical outlets. Missing ceiling tiles in hallways. Carpet is dilapidated. Shower didn't drain... water was up to my ankles before I was done. Crappiest hotel we've ever stayed in by far! View full site to comment or like
