I've been thinking lately about the term "fast food." It seems to me that we call the quick snacks that we pick up on the run "fast food." This term can have a negative connotation. When we travel in other countries, we're more inclined to think of the food that we get from a cart or a stand as "street food." And when street food is good, it's very good.
Today I'm writing about my street food tour in Chicago. It started accidentally, on the way to the bus stop. We saw a big sign above a small place called Fast Track, proclaiming that they were "#1 in Chicago." We had to go in to investigate.
