As you descend the two flights from Mandalay Bay's main concourse to Aureole you are stuck by the tower of wine in the center of the staircase, a promise this Michelin rated place will be worth  the price.  Reception is more efficient than welcoming and you are soon escorted to your table.  For such an apparently sophisticated locale dress is remarkably casual.  My coat and tie were in the minority, as was my touch of gray hair.  We have been there twice and both times the clientele was predominantly 20 and 30-somethings and in shirt sleeves and fashionable jeans.  Ask for a table in the back near the waterfall and swan pond.\n\nThe wine list is indeed impressive, but is presented on what must be the original pad computer.  It requires a stylus, is balky and is as non-intuitive as can be.  Come with an idea of what wine you want and insist the sommelier operate the damn thing for you before she slips away.   Service overall was excellent though it was Valentine's Day evening and the place was packed.\n\nWe both ordered fish, perhaps not the specialties of the house.  The swordfish in citrus with vegetables was beautifully presented.  The root vegetables were partially peeled with the skins tied into butterfly wings.  The fish was only good by comparison.  The red snapper, characterized by our waiter as flaky, was under cooked and flavorless.  It was presented on a bacon infused bed of vegetables that were much better than the fish.  The side of root vegetables was uniquely spiced and delicious.\n\nThe star of the meal was the onion soup, presented under a pastry shell the waiter cut open.  Excellent.  For such a highly rated restaurant the evening was disappointing.
