The casual wine bar, bar à vins, is a French institution. There are gritty old favorites in even the poshest quartiers; places where locals hang out over a Pouilly Fumé or Côtes du Rhone and share a moment with friends. Wine takes backstage, merely a social lubricant to keep the conversation flowing. Au Sauvignon, Le Sancerre, Le Rubis and Le Baron Rouge are some of the best examples of these traditional strong holds that serve light snacks and plenty of good will. There is a new trend on the wine bar scene, caves à manger, where connoisseurs go for excellent crus of natural and artisanal wines paired with refined dishes. Vingt 2, Le Baratin, Juvéniles, Le Verre Volé, and Café Trama are popular places to savor the new concept.
