I ate at Nougatine while on a mini-vacation.
I thought the food was some of the best I had ever had. Better than the meal a few days earlier at Daniel. (although one dinner is not very much to judge a restaurant on). I had the crab appetizer with papaya - one of the best things I have ever tasted. Lamb & risotto dish was also excellent. I savored every bite of the appetizer & main course. Dessert was okay but not special.
There were some disappointments with the meal also. 1) Service was not very good. As an example - they either wanted to give me bread or take my bread plate away as soon as I had finished the last piece, saying that they would get in trouble if my bread plate was empty. Seems like they could come up with some sort of symbol. For simple questions about wine by the glass they had to get the sommelier.
2) The bread seemed stale, and was not very tasty. I tried both varieties available. Since the main restaurant was closed the day I was there - I wondered if it was cooked the previous day.
3) The bar area was noisy - hard floors and walls made it pretty loud. I like a little noise, but seemed a little excessive.
I was eating alone. They did not have a problem making a reservation for one, but the small tables were put in the back corners. I would have preferred being able to see more.
Conclusion - I would get into the main dining room if at all possible.
