Review for Rio Hotel & Casino Review For SmashBurger Google User Jun 19 '18 at 23:21 Wow my partner and I live in Vegas for 21 years now. We would always appreciate this restaurants courtesy and cleanliness until today! It is dirty, the floor is greasey and food all over. The AC don’t work, and the food was basically just thrown on the serving tray. The person at the register was not friendly or welcome in any way at all. We just wanted to eat and leave. I suggest you look for another location this one has gone down hill.... View full site to comment or like
