And crumbs are called 'miettes'. Kind of cute, really.
Kate and I often buy sandwiches at this place. They have small baguettes, maybe 10 or 12 inches long, with ham, sausage, cheese, or crudites (tomato, lettuce, egg slices etc). Then we take the sandwiches to the park across the street and eat them on a park bench and watch people. Very pleasant.
