We had reserved a table in advance which was ready for us on our arrival. The restaurant has a contemporary feel to it and the menu is modern French. The food, ambiance and service were all very good and we were pleasantly surprised that the bill was very reasonable.
It has a very relaxed feel to it and we were able to have a conversation without feeling that other customers were too close to us.
Cote St Martins is part of a chain but it certainly didn't feel so. We would definitely recommend.
