Review for Hard Rock Hotel and Casino Sioux City Review For Hard Rock Hotel and Casino Sioux City Google User Aug 17 '17 at 22:36 The Hard Rock Casino is fairly spacious with decently high ceilings as far as Midwestern casinos go. I've been told there is ventilation systems starting from the floor moving upwards, and I will say it was less smokey than other casinos I've been. Staff was fine, no major complaints, but no big wow factor either. Overall worth the trip. View full site to comment or like
