I flew the A380 - LAX-LHR - today and chose 59A.

Pros
- Very quiet (only business people in the nearby bulk head row). You felt like you were in your own private cabin
- Obviously direct aisle access

Cons
- Extremely slow and inefficient service. It took ~ 2 hours to receive my main meal and then they didn't collect my tray at all (I went to sleep and woke with it still next to my seat 4+ hours later)

Wasn't impressed with a few aspects of CW - not great that you can't watch the tv whilst taking off. Seat arm rest was extremely loose. Obviously had to ask separately for eye mask + ear plugs. And those loos - they're massive! Why?
