This place definitely has the correct reputation as one of the best restaurants off the Strip. The only (somewhat lame) reason I don't give this a 5 star rating is due to the somewhat uncool location and (very nice but) unforgettable atmosphere.
What is not forgettable, however, is the quality service and tremendous food. Dining here more than a couple of times, I have always noticed the chef/owners are highly involved with quality control in all aspects. While you would expect this based on the menu prices, they deliver just right on that expectation.
The chef's tasting menus have never let us down, and the wine selection is one of the best in the city.
For the tourists in Vegas, it might be a $15 - $20 taxi ride (each way) in which I might not suggest it's worth that much trouble. But if you have your own ride, it is absolutely worth the trip as it compete with any other "high end" restaurant in any of the Las Vegas Strip hotels.
