Le Petit Marché, 9 rue de Béarn (Métro: Chemin Vert), ☎ +33 1 42 72 06 67. Open noon to 2:00AM every day. This is one of those charming little Parisian bistros which is off on its own a little. The wait staff couldn't possibly be friendlier so this is a good place to bring people to show them how nice Parisian dining can be. The food is in a higher class than the price range, and the folks who work here have an easy collegial or even familial way with each other, and with frequent guests.
