At a genuine French restaurant (French owner, waitstaff, menu, music, everything), I ordered steak and potatoes, but I also tried the following:
--three kinds of cheese (Camembert, Roquefort, and something else)
--bone marrow (it had the consistency of chicken fat)
--Fois gras (goose liver pate)
And now that I'm back home, my culinary adventures are over, at least for now. Eating this way all the time is expensive!
