My son and his lovely wife treated us to a meal at this restaurant. It was wonderful. I would have been intimidated by the prices but my son wasn't so we relaxed.
Everything that was ordered was passed around like the tourists we are and was stunning. The wine suggested perfectly complemented the food.
If you can afford it, do not miss this place. You will need to book obviously.
10 minute walk from Lognes train station.
Go for it.
