Le Bistrot d'Antoine
You won't find any "concept" cooking here, just pure French bistro fare at its finest—beef salad with anchovy dressing, butter risotto with truffles, sliced leg of lamb, and traditional pork casserole. Save room for the day's dessert, perhaps the wonderfully warm peach-and-frangipane tart. The prices here are as appealing as the menu. If you can't score a reservation, try one of the two Peixes restaurants (4 rue de l'Opéra and 5 rue Bonaparte), where chef Antoine Crespo serves delightful seafood tapas.
