Need restaurant/food shopping tips for 1 week in Paris with infant in apartment by Châtelet Metro Station

[yehfromthebay]

We're heading to Paris in July with our 3-month-old baby for a week in July (yes, will be there for Bastille Day). Looking for tips on where to eat with an infant as well as where to pick up groceries. We will be staying at an apartment with an American kitchen and plan to make quite a few meals in. The apartment is located in the 4th Arrondissment, a couple blocks from the Châtelet Metro station. We're willing to take public transportation to markets, etc. for groceries. Thanks!

Get some Bordier butter. I don't know the closest location, but it is available at the 'food court' at Galleries Lafayette (make sure to visit the dome at GL regardless). While you're there, don't forget the Aoki pastry stand. The green tea 'dome' pastry is a triumph.

And, no, I do not have a fixation with domes.

Bordier butter is also sold at Les Papilles Gourmandes on 26 rue des Martyrs and Ferme St Hubert on 36 rue Rochechouart.

And the little, very good, cheese shop run by the Japanese lady on rue Richelieu next to Juveniles wine.bar.

There are many food shops in the Châtelet area, which is the center of the center of Paris.
There is a huge number of supermarkets, and more than one market (Montorgueil, which is a permanent market, and St Eustache and Baudoyer, excellent weekly markets) around Châtelet.
Not knowing your apartment location, I would suggest that you ask your landlord for the addresses to the nearest supermarkets and markets.
