Review for Hard Rock Hotel and Casino Sioux City Review For Hard Rock Hotel and Casino Sioux City Google User Jun 25 '18 at 3:16 We enjoyed our time at the casino and restaurant. We walked out $100 up, so that's a big win. We each got $10 free to use how we wanted on the casino floor. They offered a free t-shirt for one hour of play, but that is not an hour spent on the floor. It is a full hour plugging money into a machine. Just a warning. The restaurant was very well kept up. The lunch menu didn't provide a ton of options, but there was decent variety and the food we got was good. If you've never been to a casino and smoke bothers you, you better brace yourself or find something else to do. It hits you like a brick wall five foot from the outside doors.
