This pretty menu is undated, but the cover brags that the dining and observation cars on the Empire Builder are air conditioned, which dates the menu to 1934. By 1935, Great Northern had air conditioned the entire train.
The menu features full dinners for 50 cents to $1.25 (about $9 to $22 in today’s dollars). Entrées include “various” fish, sirloin steak, fried chicken, roast lamb, and more. The best deal is the full sirloin steak dinner, which is just 25 cents more than the a la carte sirloin steak.
