Review for Rio Hotel & Casino Review For Royal India Bistro Google User Aug 18 '18 at 3:40 The second best restaurant in the Rio Hotel. Good Indian but service is not that great, but I blame that on the hotel more than the restaurant itself. The cooks definitely know what they're doing although I think they turn the heat down for the tourists. I like my vindaloo with a little more kick. View full site to comment or like
