I read that Delta in Comfort serves Beer/Wine on short flights so I was wondering if in First Class will they offer the full service with spirits? In Comfort I really don't expect much .

I have a flight in First and the AMEX lounge access so it really won't matter as I plan to go to the Centurion Club in December at LAX or Sky Club.

Which is the best Sky Club at LAX? I know the AMEX has better liquor .
