The only shop of its kind in Paris - only devoted entirely to ham

Caractere de Cochon

Found in the Marias, this closet-like space is filled with every kind of cooked and cured hams from various countries and just about every region in France with a variety of pates, terrines and antipasti and sausages for good measure.
For lunch have them make you up a traditional jambon beurre ( ham and butter) sandwich with your pick of hams.
