I'm on the CS day after tomorrow, so I'll report back if the new menu is in place or not. I'm happy to see them switching things up, though, since any menu gets tedious even eating your favorite items after awhile.
I very much agree that Amtrak is missing a potential revenue source by not stocking a higher priced more premium wine offering or two. I would spring for a better wine if it were available, and I doubt I am alone. For comparison's sake, I just returned from a trip out to central Pennsylvania where we ended up eating in a casual-chain-restaurant one night. (No need to call them out by name, though if you're thinking it might be named after a Rolling Stones song, you win...) While they had several red wines on the menu at a selection of low to medium price points, the only one in stock was Yellow Tail. Our waitstaffer cheerfully admitted that this disappointed many of their customers, most of whom decided not to bother ordering wine at all.
