I visited a market with a friend the other day, new to me, and found some new things. The market was on Boulevard Raspail.
This sweet man and his wife were featured on the Food Network in the States for their foie gras. He was very nice, gave us a taste of what he sold and showed us a photo of their place near Bordeaux.
