Complicating matters is a significant seasonal variation in traditional kaiseki with the winter menu being quite austere compared to the other 3 seasons. In winter you get things like 3 grains of rice precisely positioned in the middle of a dead leaf of just the right colour. I have no info about CX's catering operation, just my personal recollection and I recall one lavish kaiseki meal (and another lavish lobster thermador, also on NRT-HKG, which put SQ's "book the cook" lobster thermidor to shame). In any case HKG-NRT-HKG has nicer food than TPE-NRT on CX F, for example.
