6.6 Braisenville, 36, Rue Condorcet in the 9th (Metro: Anvers), 09.50.91.21.74, closed Sundays, opened about a year ago and went on my "Watch and wait list" due to the warning that it served "Le soir seulement." But as I've learned, places, as they mature, add lunch - the economics alone force them to. When the place we were actually headed to was boarded up at 12h30, we schlepped over a few blocks to my "back-up" and had a very fine meal indeed.
My ex-restaurateur/ex-vintner dining partner ordered the bonito with cucumber, yogurt and mint and i chose the duck breasts (for the third time this week they were featured) with microtomed cauliflower and cilantro (aka coriander) and both were exceptional.
Then she had a Black Angus bavette with an almost raw half-carrot, which allowed its full taste to zing through, and a squash puree, and I had a piece of merlu from St Jean de Luz (that she deemed the best ever) with lemon and (properly) undercooked peas. Wow!
Go? You're missing something very special if you don't.
