Delta Sky Club Int'l Terminal SFO
Just back down the corridor, the Air France l'Espace Lounge doubles as the Korean Air Lounge in the morning.
Didn't pop into the Asiana lounge but it has the most impressive entrance of the lounges.
Believe it or not, I'd almost have preferred the Delta Sky Club which is much more conveniently located on the concourse level and with, hands down, the best lounge views in the terminal. Pleasant dragon thanked me for being a Delta Diamond Medallion and explained that although Delta now only operates 5 weekly SFO-Tokyo Naria flights, they are generally quite busy as the lounge is used by KLM, Air France overflow, Air Berlin and Air Canada among others.
The great view from the Delta Sky Club...
In the concourse itself, presumably Emirates outbid Cathay for the primo concourse level location.
One stop for a new trashy spy novel and it's back upstairs to round up the group, who were surfing the internet using the free Cathay wifi. Classy wifi password card.
