The real specialty at this classic, luxe shop is Armagnac, with vintages dating back to 1868. Don't know the first thing about Armagnac? Just ask, and one of the friendly staff will pour you a taste. The back room houses an impressive collection of first growth Bordeaux (Margaux, Latour) and Chateau d'Yquem, and R-D bottles their own lines of port and Scotch, too.
