Just discover this French mediterranean restaurant. I will describe it as a French version of Cipriani (Mr C.) ... very Mayfair Chic, the action is in the dinning room (people watching) not in the plat. The cuisine is good but not outstanding. It is probably the only restaurant who you should be serve by French people and you are not (just a small detail...).
They have restaurant in Nice, Dubai and New York. The concept is order plenty of different dishes and them share.
Make sure you reserve and be on time....as in all the restaurants in London.
