The quality of the Feast at GVR has consistently gone downhill since 2006. You can now get a dinner buffet for just under $12 here.
The food isn't bad at all, but it's definitely not up to par with the upscale GVR. Service has always been terrific. Definitely use your players card to get the discount. Don't expect the Bellagio and you'll be happy.
The top advice I can give is to hit the Mongolian station! Yummy!
