One last Coast Starlight update- they were out of the kid's mac'n'cheese by the first (11:30am) seating of lunch the second day of the trip, leaving my 9 year old with a choice of... a hot dog. The server groused about the newly limited menu in general, and kids menu in particular, especially with summer starting (lots more kids on board soon), and my daughter kind of cried (her second choice, in her head, was the grilled cheese... she KNOWS they run out of stuff so was prepared! But I had utterly failed to warn her about the reduced choices).
We did our best to be reasonable, agreeing that the reductions kinda sucked, and my kid and I ended up splitting an Angus burger and she was supplied with her own serving of potato chips at no additional charge.
