On some trains, the French toast may be available, but only in one direction. Going west on the Cap & the CZ in 2011, only pancakes were available but I was told the French toast was available eastbound.
That appears to no longer be the case… looking at all of the routes on Amtrak website none of the routes have separate westbound and eastbound menus.
It also appears that there are only two different menus in use:
Version 1 is in use on most of the western trains (the California Zephyr, the Southwest Chief, the Coast Starlight, the Empire Builder, and Texas Eagle).
Version 2 is in use on most of the eastern trains (the City of New Orleans, the Crescent, the Sunset Limited, the Lake Shore Limited, the Silver Star and the Silver Meteor.)
