I had the Big Sky chicken dinner in May on a trip on 27 about 5 years ago. I saw some posts a while back that the service was gone. I guess someone who has travelled on the Builder this summer can confirm this or not. It was a helpful and convenient service so it probably is gone.
I rode Empire Builder 7/27 and 8/28 in both directions back in July, and sadly I can confirm those are no longer sold on the EB. Honestly if one is in coach and is desperate for food not from the cafe car or dining car, your best hope would be to find food somewhere near either the Whitefish Amtrak stop(IF you rode that far west, once heard a report of someone SOMEHOW running to Great Northern Brewing to get a drink there, then somehow making it back in time before the train departed. I'd ONLY be open to trying that, IF 7/27 was early into Whitefish), Havre(I saw a bar and casino with food, PJ's, was across the street from the Havre station), or Minot. For the latter(Minot), I know there's a coffee truck and food stand(out of a truck) called Daily Buzz that's open from Monday-Saturday(thanks to 3 people on google maps who confirmed this, when I asked a question about the days they were open on their google maps review page), that westbound 7/27 train travelers(Daily Buzz btw is closed when eastbound 8/28 arrives into Minot) could easily walk to during that extended station stop. There's also the option to see in Minot if you could call a nearby restaurant(i.e. the fact I saw a Thai restaurant in downtown Minot, along with a pizza place just north of the bridge of the road that has an overpass just to the east of the Minot station), and see if either place would deliver to the Minot station house while 8/28 does its station stop there.
Also I'll note for Havre, there are a few vending machines inside that station house on a side wall within the waiting room area. Shelby, MT also had a few, as well. I didn't ride all the way west to Whitefish(only to West Glacier), so can't report on the status of that station. I wish the EB still sold those Big Sky chicken dinners, though! Was this sold out of the cafe car, on the lower level of the Sightseer Lounge?
Fried Chicken Dinner. Loaded In Havre Montana. Might have been Shelby. This was being sold to coach passengers, but I decided to buy and try it.

Ah, so that's what those sometimes talked about Big Sky chicken dinners were like! Thanks for posting these 2 images. I see with the HAV sticker on them, that they had to have been from some local place out of Havre. Too bad those are no longer offered on the EB, if they were sold at least as late as 2015(per those 2 pics over on flickr). Sigh!
