Home Away From Home

Duchess and I try to stay here when we come to Paris for our shopping trips and tours.  It's is a large secluded square in the heart of the city with everything right outside our door.  Some of the shops change hands but the restaurants remain some of the most famous in Paris.  If you follow this down to the end of the square and pass through the large archway you'll find the restaurant made famous by Diane Keaton and Jack Nicholson in the movie "Something's Gotta Give".
Do you know this square?
A bientot,
