This was about my 10th time over almost 40 years. Yes, it has been there that long. In fact, the building is from well before 1500 - so it is kind of ancient and the ambiance reflects this, but in a nice way. Very cozy - a sort of place you want to bring out-of-towners for a "memorable" meal.
The food was "ok": I had the tuna crusted in sesame (no where near up to standards in New York for this dish), my daughter the fliet de bouef, and my wife the magret de canard. The filet was decent, and the duck pretty much the best dis of the lot. As a starter, my daughter and I had the snails (yum - but hard to mess up).
I think that the same meal substantially could be had at any one of a hundred brasseries in a two mile circle of this restaurant. Some better, some worse, but most a fair bit cheaper. Go here for the ambiance. Otherwise, if it is solely food you are after, save the bucks and check out a local brasserie.
