We added this one because it can bring to mind the unknown (and known!) wet patches and liquids that you see on a sidewalk. In this scenario, you might be ordering “The juice from the sidewalk”. If you put the emphasis on “Sidewalk” rather than “Juice”, it gives the name this more “juice of the sidewalk” meaning.
We must add that we cast no aspersions on the business; in fact their products are lovely, and they do the best grilled cheese and bacon sandwiches around.
