Overall CX does the best job. All HKG lounges are very good with Pier F being the best IMHO. For lounge hopping LHR terminal 3 is hard to beat. For those who still smoke (I don't but used to many years ago) JL has very nice smoking rooms in their lounges at NRT. Overall not much can beat HKG for me. Eat at the great À la carte restaurant at Centurion lounge and then relax a the Pier.
