Inconspicuously tucked into a nondescript strip mall, Plein Sud defines the term quiet little bistro. No star chef, glossy magazine ads, or featured appearances at the South Beach Wine & Food Festival. No breathless word-of-mouth among the SoBe arbiters of hot spots. No marketing maven marveling at the rustic, flower-dappled décor. No PR machine boasting about the homemade foie gras terrine, blanquette de veau, or beef Bourguignonne -- which, incidentally, bursts with lusty red wine aromatics. Still, the seats are filled at this North Miami restaurant, mostly with locals who luxuriate in the unpretentious ambiance, personalized service, and authentic provincial French fare. Patrons also get a good deal, because just about every entrée costs less than $20. There are bigger and bouncier bistros, to be sure, but Plein Sud is plainly one of the best. Regardless of whether you care or not.
