List of top-rated Las Vegas restaurants:

https://www.vegas.com/traveltips/top-10-gourmet-las-vegas-restaurants/

I have dined at all but Andre's and Twist and agree you will have memorable dining experiences at any on the list. These are expensive gourmet restaurants where you should expect a bill of $200+ for wine and food. Las Vegas has definitely had an increase in the number of top restaurants in the past 10-15 years... places to visit when you are celebrating something special and have the time to spend for a fine experience.
