Aquitaine is a French bistro located in Boston. The room is lined with leather booths on one side and a long banquette with white table clothed tables on the other, giving one a front-row view of the open kitchen. French artwork, posters and mirrors decorate the space, to resemble a modern Parisian bistro. Its menu includes entrees, such as horseradish crusted salmon with green lentils, tomato confit and mustard-dill jus, and scallops au poivre with morels, English peas, parsnip pur e and sauce chasseur. Aquitaine s wine offerings cover all the important French wine regions, as well as the big California houses.
