Just got back from five days, four nights in LV, and the food was as good, if not better than I had expected given the recommendations on this board.
A few mini-reviews...
My family and I had one of our most memorable meals at a Guy Savoy-offshoot restaurant in Paris (in 2003) managed by his son. I had kept the business card/check as a souvenir. When I heard that Guy Savoy had opened a restaurant in LV, I, my wife, and kids were all truly excited.
Well, we made reservations, and even though I knew it to be expensive, it was trop cher by some geometric factor. Certainly you are treated like royalty, and my 17-year old loved the pampering; my wife found it somewhat intrusive and offensive.
After showing Monsieur Savoy my Paris souvenir, and having him seem genuinely pleased that had returned to another of his restaurants, we opened the menu to be utterly shocked by a la carte prices of $60-70 for appetizers and $80 and up for entrees. (I had thought we could avoid the over-pricing by not choosing the prix fixe or tasting menu, but for four people, with wine, tax and tip, you are approaching, if not exceeding, $1,000 for a single meal.) I couldn't--wouldn't spend that much. This was possible three times as expensive as the food prepared for us in Paris; coming from New York, I thought I was victimized by Il Mulino charging me $27 for bottled water! But in comparison to GS, Il Mulino, any restaurant I've ever eaten in, is like fast food. So what I had eagerly anticipated turned into one of the most awkward meals of my life. First, they decided that my 17 year-old couldn't drink wine. (On the positive side, that meant I didn't need a full $68 bottle given how little I drink. Ordering wine had been a bit of an ordeal. The list is vast, contains bottles for $7,000, and when I mentioned "low end" to the son, he seemed to regard my suggestion as the equivalent of some horrible crime. When I asked him about a $35 bottle he made me feel as if I was failing some essential test.) Then I had to tell Monsieur Savoy that the place was more expensive than I had expected, and therefore, my family would only be ordering entrees. He was kind enough to send a tasting portion of soup to the table. But $80 per entree is still absurd any way you look at it; I had a check of over $400 just for four entrees and two glasses of wine! (and a very unhappy wife and children). I love food, and everything at GS was superb in terms of taste, but at what price? In NY, we're used to what I consider over-paying at half that price.
The following night, we went to Rosemary's, and had a much more relaxed and enjoyable experience. In contrast with GS, Rosemary's seemed like a bargain: it was essentially the same price that I had paid at Savoy, but included four appetizers, four entrees, and four desserts, plus wine, soft drinks, tap and tip. Rosemary's was as good as promised, and more sane in terms of pricing ($50 prix fixe pp).
Tried next to go to an Italian place called Nora's, but it was closed on Sunday (which seems odd) and wound up at a nearby place, Ferrara's, which was ok.
Finished the trip at Lotus of Siam which was just great...the best Thai food I've ever had, although my wife who has it much more than I in NYC, was not as impressed.
The bottom line is that LV is a great town for people who enjoy food.
