ONE 777 has NGBC seats so far. Your chances are very slim.

The late flight like that will have a more rushed service. Food tends to be chicken, beef, seafood or pasta. Pre-made Sundae.

The late (last) flight from ORD is a very rushed service and they want you to eat fast and go to sleep. It's not the 'all at once' but it is not the leisurely courses of earlier flights.
