Food service was available on my Auto train trip April.
We had dinner delivered to our sleeper room last week. There is no dining car though. They give you a menu and ask what time you want your food delivered. It wasn't bad either.
No dinner service just cereal, banana, milk, a breakfast cake and a water was all we had going and coming back but was relaxing and 13 hrs if no driving down straight long roads boring roads...it was great for us!
