The archive includes more than 17,000 menus from restaurants in New York and lots of other places, and the oldest ones date all the way back to the 1850s. You can even help index the items on menus any time you feel like productively procrastinating.

One especially neat thing is that a handful of the places that were open in New York back in the early 1900's are still operating today (in some incarnation), so you can see how much their menus have changed in the past century.
