I expected more out of the prestigious Bellagio.
Myself and a few friends stayed here for my 30th birthday this past November. Our room was fitted with 2 queen beds. The service at the Bellagio was average. The room was very average and compared to Mandalay Bay was sub-par. We had plumbing issues where the faucet would drip and not drain well. The shower and tub were very average, there was no flat screen TV's or anything fancy.
The plus side to the casino is the art. The famous glass ceiling is astounding and the walk through art items are a delight. The fountains are beautiful. The night club at the Bellagio is called The Bank and is very average though the DJ was good. We ate at Yellowtail sushi and it was good but not great. The Bellagio buffet is tasty but doesn't hold a candle in the wind to Wynn's buffet at the Wynn resort thanks to the fact that he sold the Bellagio a few years ago and it is now corporate owned. Anytime this happens things start to slide.
My recommendation is that if you want to stay in a 5 star casino don't spend your money here. Go to the Wynn, Encore or even Mandalay Bay for a better experience.
