Paris means great food. Some tips:
Chez Mamy, 3 Rue Jules Vallès, 11th arrondissement, very nice, simple Paris bar with a good menu. Ambiance is great with a very friendly Patron..
Restaurant “Chez Janou”, 2 Roger Verlomme, 3rd arrondissement chez Janou. People were queing outside to get a table. What else to say..
Aux Bons Crus, 7 Rue des Petis Champs, 1st arrondissement, fantastic little restaurant behind le Palais Royal. This was our biggest discovery while looking for a place to lunch. Simply great!
And while in Paris, you should certainly visit the maison européenne de la photographie / ville de paris mep-fr.org. Especially the show ‘Rome + Klein’ on William Klein in Rome is worth a look! and so are the portraits by Martine Franck..
