Quelle belle découverte sur la rue de Grosbois. Tout était frais & servi sur des plateaux avec ce petit papier à carreaux rouges qui donne une touche vraiment classique.

Les burgers sont généreux & les portions de frites accompagnées de ces bâtonnets croustillants sont parfaites pour partager. J'ai aussi beaucoup apprécié la généreuse quantité de petites sauces servies à côté. C'est exactement ce qu'il nous fallait pour un repas satisfaisant.
