For those of you who SAY you want to experience an authentic old time Paris bistro; I think we found it today.
Bar Fleuri, 1 rue du PLateau (19th) M Buttes Chaumont.
Poulet Fermier / Frites 7E, Saucisse/Lentils 9.5E, Rillettes du Canard 4E, 500ml Rose 6E. Not fancy, not gourmet but all very good and satisfying. Poulet as good as any you'll see roasting on the streets. Tiny space with friendly attentive service. Neighborhood place where you are guaranteed not to see any tourists.
