Two and a half stars. Been here a couple times. Perfectly adequate. Nothing particularly standout or noteworthy, they serve up decent food at decent prices. Avoid the wine by the glass if you can. Their bottles are relatively cheap for what you get ('08 Silver Oak Alexander Valley for $68?? Do they know what a bargain that is?).
Their cocktail menu leaves a lot to be desired. Every manner of vodka mix imaginable, but no (or very few) whiskey cocktails. Guys, get with the times.
They have a huge screen with a grainy CCTV view of the falls. Not really sure what the point is, but it's huge, garish, distracting and out of place. If you don't have a river view, don't try to fake it.
