Recently, I got into a discussion with someone about the origin of the word bistro. The person that I was talking to attributed the origin of the word to the word for quick Russian, when the Russians went to French cafes in Paris after the defeat of Napoleon. However, somewhere in my reading I have come across the notion that this story is apocryphal, but I can never seem to remember the source of this idea. Does anyone have any thoughts about the origin of the word bistro?
