Does the Cathay Pacific First Class Lounge have a buffet? I am interested in buffet lounges. Can you give me a recommendation on which lounge to visit, in any order? I like to visit the buffet and have a shower. 

Do any of the Oneworld First Class Lounges have buffets and if so, which is better? 

I would like to see either Emirates and/or Etihad join Oneworld. Maybe China Southern Airlines should join Oneworld.
