Just saw this thread...interesting. Comparing the menu with my Zephyr ride a year ago:
Breakfast looks like the same thing just with puffed up phrasing and the added egg bowl.
Lunch - I liked the original chicken salad, it was great since you were sitting on the train all day. I'm not sure I'd go for this "Southwestern" version with guacamole though. And it's probably preprepared so you can't ask for it without it.
Dinner - Better the ACAT chef stuff than the supermarket TV dinners, although that still seems to be on the menu. The shrimp looks like an interesting choice, and the $36 combo looks like it costs Amtrak nothing in terms of space since it's the same ingredients as the steak and the shrimp entrees separately. Accounting gimmick it is.
I notice the note about lunch items being available for dinner is no more.
No more ice cream?
