Expensive, but worth it
Las Vegas is home to some of the top restaurants in the world... with prices to match their prestige. The following aren't cheap, but are more than worth a splugre, as the food and atmospheres are top-notch.
(NOTE: If you want to enjoy a meal at one of these spots you should contact them ahead of time to make a reservation. And by "ahead of time" we mean a month to six weeks before your trip.)
Aureole at Mandalay Bay
A creation and sister restaurant to Charlie Palmer's Aureole in New York, this restaurant is best known for its extensive wine selection and for its "wine angels" -- sommeliers harnessed to bungees in order to navigate the wine tower. Aureole's seasonal menu changes according to ingredient availability. "Progressive American" fare mostly constitutes fowl and beef with some creative sauces. You can order a la carte or for a more complete (and slightly less expensive) experience, multi-course, prix fixe menus with or without wine pairings are available.
SW Steakhouse at the Wynn
One of the nicest steak and chop houses you'll ever enjoy. Especially if you have a couple of glasses of robust red wine before looking at the bill. If outdoor dining is your thing, ask to be seated on the patio overlooking the casino's lake.
Restaurant Guy Savoy at Caesar's Palace
This place is heavy on the French cuisine and long dining experiences. It's not a restaurant you can just duck into for a quick bite. It's a place to sit and savor for a few hours. If you're a true gourmand and don't mind shelling out the big bucks, the 10-course Menu Prestige could be the highlight of your trip.
The Grotto at the Golden Nugget
The Golden Nugget dominates the high-dollar selections Downtown, as that part of town isn't geared much toward the Big Spenders. The Grotto features excellent Italian food, and with the right seat, a nice view of the hotel's swimming area.
