Review for Argosy Casino - Sioux City Review For Argosy Casino - Sioux City Google User Jul 15 '17 at 3:31 I didn't like it. I'd suggest paying a little extra to stay somewhere better. Room was clean except for the sticky bathroom floor and the heater/air-conditioner worked, but it was busted and a little loud. Breakfast buffet was not good. They had buckets on counter catching dripping ceiling. Also, parking lot and neighborhood were shady AF. View full site to comment or like
