Review for Rio Hotel & Casino Review For Hash House A Go Go Google User May 5 '18 at 21:24 You need to post your proper hours correctly on google. I came in this afternoon, at the Rio Hotel & Casino, thinking you were open. As mentioned before, this location has unusual hours i.e. 7am to 1pm. Get with the program Google. The menu differs from the other locations, it does not have the new items like the red velvet pancake. If Star Trek or any sci-fi convention is at the pavilion, you will get a chance to see a few stars eating here. View full site to comment or like
