Rick Meyerowitz and Maira Kalman made an elaborate map version of the NYC subway where the names of all the stations and landmarks were replaced with food names.
Train of thought: Rick Meyerowitz explains on his site how the gastronomy idea came about.
September 2003: I was on an A train headed downtown. I was absentmindedly staring at the subway map and thinking about lunch when all the station names on the map suddenly rearranged themselves in my mind to become food-related names. “That’s interesting,” I thought. “What if I redid the subway map to make it a food map?”
