I can confirm the recommendation of 6 Bosquet restaurant. A friend introduced me to it in January, and on a trip in May another friend said it "may have been the best meal she's ever eaten." Granted, she doesn't get out as much as most of us, but still a good recommendation. Our total (including tax & service) was only about $50 each, but that only includes ½-bottle of wine (albeit a good one). The only drawback: they allow smoking (this is Paris, of course), including cigars. I counted 6 lit in the room at once. Fortunately, we were on dessert as the smoking started, so left quickly.
