It's been a while since I took a Delta transcon red-eye, and I'm wondering about food offerings.

Looks like I'm going to be flying FAT - ATL on a flight leaving at 1030pm and arriving at 548a.

Is there real food for purchase in the main cabin after 10pm? And is there a real meal or sandwich snack in first?

As a diabetic, I always bring along some food Just In Case, but I'm wondering if I can expect a choice of food on the flight.

TYIA.
