The Pier offers one of the best first lounges in the world. For instance I’d rank it behind Lufthansa’s first class terminal, largely on par with the Qantas first class lounge in Sydney.
Ultimately the restaurant is fantastic. The private rooms (with curtains) are great, I just wish the temperatures there were more adjustable. The shower rooms are wonderful. And there’s modest spa service. That combines to make an incredible lounge.
