Le Bon Marché sells Lucky Charms, the US breakfast cereal, at somewhere near 13€ a box. Elsewhere in the city, they are available at half that price which itself is probably 3 times more than what they sell for in the USA.

Le Bon Marché has many interesting items but what they charge for many is far above what you´ll pay for the same item at the new Carrefour supermarket just to south on rue de Sèvres.

If you go to La Grande Epicerie plan it around lunch time and you can have a very nice lunch at one of the in store cafes. And as basic supermarkets go I loved the Monoprix on Rue Rennes- the downstairs market has an in house meat and cheese counter which you don't see often in the states anymore and lots of French food stuffs. I could spend hours there- in fact i did...

Go to the rue de Levis Market ! You'll love it

That is a market street, not a street market. Yes, it is nice, but there are so many others like it. However, rue de Lévis was my market street for 2 years back in my early years in Paris, so it holds a special place in my heart. Unfortunately, I have found far better street markets since then... (Just for the record, a market street is just a shopping street lined with food shops. It is not like a street market where there are special stands set up twice a week.)

Agree with you Kerouac. I live nearby rue de Levis. Food stall now seem to be owned by same guys. Street is gradually taken over by the usual chain stores. For food, I go now to the organic market every saturday on Blvd des Batignoles. Also very popular with tourists. Maybe the sunday version Blvd Raspail not far from la Grande Épicerie is even more popular for tourists, especially for Japanese and we know they are serious on good food.
both are real street markets like the farmers markets in US

Paris street markets are not generally farmers' markets. Because of your interested in markets, this is the website of the farmers' market I use. Maybe you would like to take a look at the set up. Orders are placed in advance and the stuff comes in from Picardy for pickup.

Kelbongoo!

Thanks a lot for all this additional input - everything is noted, and we‘ll try to explore as much as we can of your suggestions.

Since we won‘t stay far from this year‘s winner of the Grand Prix de la Baguette, at least bread should be in good supply
