Review for Argosy Casino - Sioux City Review For Argosy Casino - Sioux City Google User May 28 '18 at 12:28 This is one of the worst hotels we have ever stayed at. Terrible rooms: bathroom doors don't shut, no hot water, tiny and dirty bathroom. Not so dog friendly: no grassy areas on the entire lot for dogs to go to the bathroom. Horrible breakfast: limited options, fake tasting food, watered down coffee. It's safe to say we will never be staying here again. View full site to comment or like
