In terms of bang for your buck, I gotta give it up to the Bellagio.  First of all, the Bellagio is one of the prettiest hotels on the strip, so its worth a visit regardless of if you eat there. The buffet (I've been for dinner) is simply enormous.  One of my dining companions counted the different types of meat and fish he ate and I think he ended up with 15+...I don't know of too many places with that kind of spread. Plus, the food is generally of a pretty high-quality.  It may not be 4-star dining, but you are also not paying 4-star prices for it. If you need to rest your stomach afterwards, the fountain show in front of the hotel ain't half bad.
