This restaurant in a traditional old building with a pretty patio to be enjoyed on sunny days has a small lemon-yellow dining area (echoing the name Citron) with exposed stone walls and modern bistro furniture. Éric Sampietro (previously chef at La Table des Cordeliers) concocts appealingly hearty fare, from vegetable broth with pork dumpling to roasted pear with ginger caramel, crumble and yoghurt ice cream.
