This menu dates from before 1909, when NP began selling its Great Big Baked Potato. Other than the fact there are no giant spuds on this menu, there’s not much to date it except for prices.
A sirloin steak was $1, which if the menu were from 1908 would be about $25 today but if from 1900 would be nearly $30. From 1890 it would be closer to $25 again as the late 19th century was a deflationary period which ended in 1899. So I’m inclined to think either 1890 or 1908.
