In a narrow street near the Doubs, this couple, who earned their stripes in prestigious establishments, work in tandem in the open kitchen, occasionally venturing out to serve diners. Their single set menu, based on carefully selected seasonal produce and enhanced by wild-picked ingredients, is akin to a natural history lesson: carrot / marjoram / plantain / burnet / bay leaf; black pork / pumpkin / poultry jus / spring onion oil; beetroot / raspberry / coriander / iced nougat.
