We've all heard about the decline of airline spending on food services, and we all complain about it, but I was wondering:

What is it really worth to you? How much would you expect pay for that meal you were just served on the plane, if it had been served in a restaurant? (I'm most interested in hearing about the higher end first class stuff -- ranging from common airlines to carriers like SQ)

From my experiences, I would say that I have received a range of (equivalent to) $15-$25 restaurant meal services on flights in FC (domestic). Anyone else?
