I agree with the others; this is a wonderful idea, and will keep it in mind for the future as something to do.

I'd say Emirates' Grilled lamb cutlets look tasty, as does the Avocado, mango and lobster with a spicy cocktail sauce.
Lufthansa's Filet of beef is presented very nicely as well, and looks appetizing.
And Air France: yikes!! It looks horrid!

But I did enjoy the photos... thank you for sharing them! ^
