After having staying in some of the best boutique hotel in Paris we want back to the real Palace and I have to say it is much much better. The Plaza Athénée is a great place the service is as it would be and even better than expected. The breakfast is delicious. They have a very trendy bar. The location is excellent on Avenue Montaigne, right in the luxury shopping district (Montaigne and close to Saint Honoré) You can walk to the main Museum (Le Louvre, Musé d'Orsay, Branly, Musée d'Art Moderne, Palais de Tokyo). Ask the Concierge for the entrance ticket it will save you from queuing up.
For a fine dinning Lasserre is a very good choice, very France cuisine and nothing molecular. It is in amazing building with a retractable roof !
