My wife and I recently stayed at The Bellagio. I have stayed at multiple hotels on the strip, and as far as the room, and the bed, The Bellagio is about as comfortable as staying at almost any other hotel on the strip.
The staff was nice, just nothing above and beyond which one might expect at the only 5 star hotel on the strip.
The turndown service was nice, except it wasn't consistent. The first night we were there, they came at 5:30, two nights they didn't come at all, our last night, they were knocking on the door at 11:15 when we were already asleep.
The food at the Bellagio is excellent, just expensive like everything else in the hotel. The buffet is really good, but, one doesn't need to stay there to visit the buffet.
Overall, I would say walk through the Bellagio and stay somewhere else.
