The West of Paris "les beaux quartiers" is often ignored by visitors, but for me it's home from home... Just spent a few days there visiting Mum, and here are some interesting restaurants:
KURA, one of the best Japanese restaurants in Paris (imho). Miles away from the sushi/sashimi you'l find everywhere. Splendid Bento box at lunch time and a fantastic set menu for dinner. Rue de Boulainvilliers.
HUITRES ET SAUMON DE PASSY. As the name implies, that's all they have, and it is best... a small place on rue de l'Annonciation, 6 tables so advisable to book.
LA ROTONDE DE LA MUETTE. A brasserie with all the right dishes including excelent oysters and andouillette (+++), warm, smiling and professional service. On the Chaussée de la Muette.
LA CAUSERIE (ex Chez Geraud), rue Vital: Under new ownerships for the last 2 or 3 years, and they have found their marks. Warm welcome from the owner, very interesting oeuf façon meurette, and always the crispy "ris de veau" / sweetbread, for which I keep going back!
LES MERVEILLEUX DE FRED: Meringue and cream is the secret there. People queue around the block after mass on Sunday to pick-up the precious dessert! Just avoid that particular timing... But the queue is worth it for an incredibly pastry, light and rich at the same time . Corner of rue de l'Annonciation & rue Lekain.
And of course the great shopping on the rue de l'Annonciation, in the Passy Plazza and at the marché de Passy (I could not resist ordering a cheese board from Androuet, discussing each cheese with the serving staff was very interesting), and for the ladies, strolling the rue de Passy is of course a must!
I visited the new Grande Epicerie on rue de Passy (did not buy anything though...) and missed its restaurant La Rive Droite, warmly recommanded by John Talbot. Just did not have time. May be at the next visit!
If you're ever lost in that part of the world, there is a lot to enjoy...
