For those planning to repeat this Kaiseki meal, it is offered by CX only in F on the non-stop HKG-NRT-HKG service. The HKG-NRT flights that stop in TPE do not have it, nor is the japanese meal in J comparable (it is maybe 25% as good). Also the Kaiseki menu varies seasonally (as it should); I find the April one to be best. CX serves about 20 of these meals a day -- that is all! I'm guessing on the number, but it is very close to that; and they do it principally to compete with JAL.
