If this one doesn't tempt the taste buds, I don't know anything that would.
This place is called Aureole and is located on Las Vegas Blvd. at the Mandalay Bay Hotel. You may have heard of the prestigious chef, Charlie Palmer who has a restaurant in New York.
They offer American cuisine and have a wine tower with over 9,000 bottles to choose from. The "Wine Angels" (wine stewardesses) are literally hoisted via harnesses to retrieve the bottles of wine.
A friend of mine dined at the New York restaurant and said it was the best food she ever ate at a restaurant.
