Part of the appeal of the martini must certainly be
attributed to aesthetics--the crystal look of the glass, the sheen of
the shaker. Purists even demand specific styling of measuring
instruments. These sites have pleasing visuals (as well as ordering
information) of elegant martini accessories. Shaken Not Stirred is a great site for a variety of martini glasses, shakers, and decorative gifts.
