I can't fault the food at this restaurant. It really was very good, from the surprise amuse bouche to the little meringues that accompanied the bill. At first I thought the portions might be a little on the small size but they were actually pitched just right because I left feeling satisfied as opposed to bloated. Beer was expensive but we noticed this to be the case in all the restaurants we ate at during this trip to Paris. I'm not sure when it became acceptable to charge 8 euros for a bottle of beer but that wasn't isolated to this restaurant so it's not really a criticism. My husband had half a bottle of wine that was also quite expensive, again this seems to be the case across Paris at the moment.
I loved the décor, the service was efficient and friendly without being too effusive and the waiters both spoke excellent English. We booked quite early, 7:30pm because I'm 8 months pregnant and finding it difficult to stay up very late. We were the only people in the restaurant until about 8pm and by the time we left at 10pm it was full. So if you want a bit more atmosphere I'd advise booking a bit later.
We would definitely return if we're in Paris again. Just bear in mind this isn't a Michelin starred restaurant. Some previous reviewers appear to have been confused about that. The restaurant itself is very clear that they have been awarded a Bib Gourmand by Michelin, not a star, so don't go expecting Michelin starred food!
