More like a 3.5 or a C as to say Average.
Ok, so let's start by saying that Buffets in general are not a good Value unless you eat like a pig. However, for me, it was free since I have loyalty points, otherwise you'll spend $26 for weekend champagne brunch.
With that said, if you are staying at the hotel, or like many options, its not bad. you could do worse (excalibur).
I do like that I can try many things, multiple glasses of champagne, however, I tend to stick to the basics... which is safer and I know I'll like it.
