Several months ago there were posts by some who stated that they had heard from Amtrak officials (not the usual OBS employee rumor) that traditional dining would be restored to the Lake Shore late this year or in early 2024.
It is now "late this year" and traditional dining has not been restored to the Lake Shore nor, as far as I know, has a firm date been set for the return of traditional dining to that train.
I will check back in the Spring to see if this gargantuan task has been accomplished by then and if not, if there are any signs that we are anywhere closer.
