It always pains me to report that places, especially those where chef-owners I've eaten with, have disappointed me, and friends and enemies on this site will say I have no right to judge any resto after only one meal. On the other hand, I get enough comments saying they like the fact that I will disagree with the prevailing wind (which according to Casablanca, is blowing from Vichy.)
To the point, Julien Roucheteau who earned his stars and stripes at the Table du Lancaster, set up shop with his lovely wife Laure in Levallois-Perret in a terrific looking but disappointing place called Je l'M; and the Delacourcelles moved from Le Pre Verre to Le Vitis in the 15th; again, just not up to their previous stuff. Just reporting.
