Dining Car food has always been extremely high priced relevant to the times; in OCT 1969 a Steak and Egg Breakfast on the California Zephyr was a whopping $2.75. A few years earlier, Coach passengers on the same train could enjoy Chef's Early Dinner in the Diner (1 seating only) where $1.25 put an entree, potato, vegetable, bread, beverage and dessert on the table.
With this trend in mind, I really do not grouse at Amtrak pricing and I find the food to be quite enjoyable.
Yes, but the food on those trains wasn't TV dinner/instant-style food heated in a microwave by a short order cook and served on a disposable plastic plate. If the quality of the food were at least comparable to Amtrak's standards from 15 years ago, your argument would have some merit. If you adjust for the differences in quality and service, I'd say that the food nowadays costs at least twice as much as it did back in the "golden days", adjusted for inflation.
As to the people who are saying that Amtrak food is similar to that offered at Denny's, I'd have to disagree. Denny's at least serves your food on real porcelain plates and your drinks in glasses made out of glass! Also, Denny's is capable of making
toast. (A novel concept, I know!)
Seriously, I had a better breakfast and dinner on two recent North American business/first-class flights with American Airlines than I did on a recent train trip on Silver Service. The food was actually marginally better on AA -- the salad was nicer and the breakfast bread was a bagel that didn't fall apart (as my convection oven-heated slice of bread did). Also on AA I got free alcohol and the breakfast omelette meal didn't take 35 minutes to prepare as it did on the train. Of course, I also was served using real plates, cups, and glasses instead of disposable plastic.
Now when you compare the business class food on Air Canada's North American flights, there's no way Amtrak* (or any US-based carrier for that matter, airline or otherwise) can even come close. The meals they serve in the "Bistro" cars on Deutsche Bahn (which use only two to three employees) are better than Amtrak, and their actual full "Restaurant" cars that are on longer high-speed trains, night trains, and select conventional-speed intercity trains are even better than that. (Amtrak doesn't even have a sit-down option on Acela, and they don't serve you real food on real dishes or your beer in a real glass in the food service car.)
*Auto Train is a whole different ball game and is not included in these comparisons.
