We make a point to visit Jean-Claude and Nathalie every time we visit Paris. First, they are our main point of supply for fine fois gras (in tins). And, second, their deli food and wine from the Southwest of France are extremely tasty and personally selected by the owners. Try especially the fois gras salade or sandwich. Great prices, even with a weak dollar. There's a line of locals out the door at lunchtime for a reason. Sit outside under the canopy to soak up the local color and the tasty experience.
