Key to the Gustavademecum

Last week, I posted about the The Gustavademecum for the Island of Manhattan, a delightfully geeky, DIY-made, mid-20th century dining guide produced by a physical chemist for the benefit of traveling scientists and engineers.

One of the key features of the guide was an elaborate series of symbols and letters that provided a lot of information about various restaurants in a small amount of space—and which look like some kind of crazy alchemical shorthand. In the original post, I included a page from the guide, so you can look at that to see the symbols in action.

Hugh Merwin, who wrote the story on The Gustavademecum for Saveur, also scanned a page from the guide's key, which didn't appear in the original story. You can see some of it above, and visit his personal website to see the full key.

    1. the classiness of this line is a bit questionable by modern standards, though i’ll grant you the rest: “14: Qw: quality of waiters. f: female, m: male. Blackface type: negro. Figures give observed estimated IQ/100.”
