The staff member did not exactly know but the menu was a bit limited when compared to the CCR's, though mostly the same. CK members seem to have the access, also JAL's F passengers, so could be busy depending on timings.

At the entrance desk, the Flounge agent did not even know how the "invitation" (it's a business card size) looked, it took sometime for her to find it. She said she thought it's bigger, sounded like she was looking for the one like the Concord Breakfast Room's.

So few passengers visit there, personally I still prefer the CX F.
