In a word fantastic! We booked a Salone lakeview suite. It was superb. There were actually hotel reps awaiting us in our room to ask if everything met our needs We ordered room service, the server offered to butter my husbands toast!! The Bellagio is a wonderful hotel with impecible service. Exactly what you would expect from a 5 star resort. They do not get 5 stars for nothing, believe me.
I guess its fair to say that the restaurants are pricey, but you get what you pay for. I expect excellance and that is always what I get. Casino was good. The Sunday Brunch is amazing. Fast drink service, decent payout. Front desk had us checked in and out in no time. I have read reviews to the contrary, but for us it was fast. I recommend this hotel to anyone who does not mind spending a little more. It is very well worth it.

Cheers
