Review for Hard Rock Hotel and Casino Sioux City Review For Hard Rock Hotel and Casino Sioux City Google User Jun 1 '17 at 14:21 Absolutely the worst excuse for a casino I've ever been in!!! I've literally lost thousands of dollars in this dump with little to no payback. Most casinos actually pay out a little, not this place. They claim their average payout is 90.4%. That is an absolute joke. This place should be investigated by the gaming commission concerning their claimed payouts. This casino has done far more harm to this community than good. If it burned down it would be a blessing. PS: I had to give it one star in order for it to post. It doesn't even deserve that. View full site to comment or like
