I will start off with why I'm taking off a star - I kept reading how they will send a limo which allows you to see the gardens/mansion. So I asked about this and was told that they will only send the limo for a party of 2 or more. I was going on my own as I've been wanting to go for years, one of the main reasons I went to Vegas and my friends didn't want to splurge for this restaurant. I found this to be such a biased reason - I might understand if it was reserved for bigger parties of 4 or 6 or more. But really? It's that big of a difference between 1 person and 2?! Given the amount of money you'll end up spending here, I found this a bit of a turnoff.
That being said, my actual experience at the restaurant was amazing. The service of course was impeccable - attentive, friendly, and comfortable. Being from CA, I went specifically for foie gras. I believe after hearing this, the gentlemen who took my order also provided a complimentary soup course which had foie gras in it. This made up for my lack of limo :) I ordered the 3 course meal (amuse, app, main) and felt it was more than enough by the end of it - especially with the bread and the chocolate cart. I don't know how people get through 16 courses!
I've dined at a number of Michelin star restaurants and definitely would rank this towards the top of the list!
