My parents lived in Paris for several years back in the 60s (ridiculously lucky), visited regularly since then, and are going back for their 50th anniversary this weekend for a week. They rented an apartment on Rue de Sevres, just a block from the Sevres Babylone metro. They both speak fluent French - my dad is a native - and have basically been there, done that to all the obvious places in Paris.
I'd love to give them some current recommendations in their neighborhood for those quintessentially Parisian, small, cozy, quiet places that locals in the area frequent - restaurants and cafes primarily, but also particularly wonderful boulangeries, boucheries, charcuteries, patisseries... anything really that will transport them to the "real" Paris.
Farther afield suggestions are also absolutely welcome (I'm having a hard time searching the chowhound site), too, but they're in their late 70s so close is good.
THANK YOU in advance for assisting me with this public service! :)
