Review for Argosy Casino - Sioux City Review For Argosy Casino - Sioux City Google User May 2 '17 at 19:19 Don't book online call directly for the corporate rates! I recently stayed here while out of town on business. You need to keep in mind, this isn't a 4 or 5 star hotel. The lobby is beautiful and the staff are very helpful. But the rooms are outdated. I booked through Expedia and paid $20 more than the corporate / business trip rate. If you call them directly, the discounted rate is about $65. View full site to comment or like
