I was put in charge of booking a very special restaurant for my Mother's 65th birthday - 8 people attending the dinner. The dinner is in one month and Blue Hill is booked. I made a reservation at Buffet de la Gare but am concerned that this might not be nice enough. La Panatiere in Rye was very stuffy the last time I dined there. I am looking for feedback on Buffet de la Gare and any other possibilities for very high end but not too stuffy restaurants.
