The dinner menu shown at the start of this thread was what I was offered on my 1/28/20 Northbound Auto Train trip. I ordered the steak and it was very good and well prepared. The Baked Potato was larger than I expected and was good as well. The salad was quite amble in size and the veggies were fresh.
Not expecting a complimentary glass of wine, I purchased in the Lounge Car a second bottle of wine before dinner. The Lounge Car attendant informed me with about the glass of wine before completing the sale, but, I went ahead and bought the bottle knowing that I would want more once dinner was over for a night cap. I took the bottle into the Diner with me and enjoyed more with my dinner. The white wine offered was decent.
Breakfast in the morning was what has been described earlier in this thread. The Bagels were in a bread basket, wrapped in a napkin, and were served warm. 4 types of cereal were available along with the crumb cakes which were wrapped in a cellophane wrapper that nearly required an NFL player to get the wrapper open. Breakfast is available from 6:00 to 8:00 A. M. Even if the train is running late--as mine was--the time is fixed. I wonder what would happen if the train is running very early and arrives before the last call for breakfast. In response to my question about how lone passengers could stay aboard after arrival in Lorton, Holly said they want us off within 5-10 minutes after final arrival at the station.
Coach passengers did have the CCC available as well as their Lounge Car.
The only complaint about food availability was while waiting in the Sanford station. There was only one food truck outside the station and what food was available was not to the liking of the person whom I overheard. There are some bagged snacks available in the shop within the station.
A caution about when one might have dinner: Dinner is by seatings. Northbound in January, there is a light train load. Only one seating was available: 6:00 P. M. When the train has more passengers, there may be one or two additional seatings.
