The French don’t “do” breakfast as Americans do in their menu. It is just coffee and croissants or bread. A few hotels offer breakfast and some also add cereal and eggs, but not many. If you take any side street headed away from the Tuileries Garden you will come upon many places serving coffee and croissants. Some just coffee and you can bring in your own pastries from a boulangerie.
There are many places up and down Rue du Rivoli as well and there is always Angelina’s, famous for their hot chocolate but it isn’t cheap You’ll find so many pastry shops you won’t know what to do with all the choices. Just grab a croissant and sit in the Tuileries!
French breakfast menu is much easier to find in Paris because there are so many boulangeries/patisseries around. Walk up to place du marche St Honore; it is lined with little breakfast, brunch and dinner places. Pain au quotidien is especially popular for their Sat and Sun brunch, very French: lots of croissants and pastries, chocolates and jams, etc.
Barlotti is nice for dinner, also Place du marche.. Don’t forget to check out the bar on the 3rd floor. Colette is your shop for one stop shopping, nice for lunch downstairs in the Waterbar. 213 rue St Honore. Angelina’s has hot chocolate and pastries to die for, on rue de Rivoli, right next to le Meurice.
