Au Pied de Cochon in Atlanta
Au Pied de Cochon in Atlanta is not related to the restaurant in Montreal.
It is, however, a branch of a restaurant by the same name in Paris which in turn belongs to a group of brasseries in Paris owned by Les Freres Blanc.
It's the hotel restaurant for the Intercontinental Buckhead, and is, generally speaking, no great shakes. It's pretty, though (assuming you like chandeliers made of glass fruit and huge paintings of cherubic pigs), and convenient if you're in the area.
