Anniversary trip to Paris

My wife and I are heading to Paris - staying near the Musee de l'Orangerie. Arriving Dec. 7 and leaving Dec. 15.
We haven't been to Paris for 27 years and are looking for a couple of great dinner experiences as well as other fabulous (but perhaps less expensive) Bistro or other moderate restaurants. We are looking forward to foie gras, escargot, and oysters, as well as cassoulet, canard a l'orange, coq au vin, boeuf bourguignon, blanquette de veau, etc. We are also very adventurous eaters as well.

We would very much appreciate some insight into restaurants, as well as time of evening to make reservations. We will probably contact the hotel in the next week or so to ask them to make reservations for us.

Any other tips or advice would be most appreciated.
