This place is pretty old and not really well-located on the Strip. it is down near Circus Circus. One day, this will be prime real estate, but today isn't that day. Circus Circus will likely come down in the not-so-distant future as part of MGM's plan for expansion. When that happens, who knows what they will do with "The Riv". And if MGM flops with the City Center project opening soon (I have mixed feelings on that one) it may be a LONG time until this part of the Strip gets a much needed facelift.
Inside, this place is old, but it is holding up because the ceilings aren't low like you find in some old casinos (think Trop). I go in for a drink from time to time. The bartenders are friendly and the drinks are cheap. That is a plus.
I usually complain about it when they tear down old places like this, so I am giving three stars. A massive renovation and expansion could bring this property up to speed, I feel. However, don't hold your breath. I haven't stayed in the hotel so this review does not cover that.
