Thanks for your recommendations. I agree Kozue is excellent. Have been there several times (my experience was the opposite - been to the PH for food many times, but never to stay!). So unless Kakiden is to be avoided, I'll probably try that instead (just for the sake of trying something new).

L'atelier de JR is indeed very good but a bit further, and I've been there already. Troisgros sounds excellent. I'll check it out straight away.
