Worst upscale restaurant in vegas.  I went with my wife and another couple.  We love great food and have tried many of the great restaurants in vegas.  This is definitely not one of them.  Our friends ordered steaks which were mediocre at best.  I had the halibut which was dry and had no flavor.  I switched it for the salmon which was dry and also had no flavor.  It didn't end there.  We got the mac and cheese which tasted like kraft easy mac mixed with chopped pieces of deli ham.  The mashed potatoes were chalky and bland.  Im really not sure how you screw up mashed potatoes that badly.  I could have done better blindfolded.  Finally, my wife had the lobster, which was just ok, not great.  Overall, the ambience is amazing, but the food just flat out sucks.  To make matters worse, the bathrooms were absolutely filthy.  Las Vegas has too many outstanding restaurants to waste time and money with this place, especially for the price! I will never go back to this place, or to another one of Ducasse's restaurants for that matter.
