I strongly endorse Eels (make sure to have the signature entree), Brion and Panurge.
If you go to Empreinte, don’t go at dinner time (it was so empty).
Petrelle and L’Office in the 9th are two other possibilities, though I’ve not been to the latter in a few years.
L’Îlot is a wonderful oyster bar in the 3rd that’s open late (but not for lunch) if you’re willing to wander a bit further. It’s great for a light meal
