The Baltimore Sun reports that workers inside the restaurant evacuated after they heard one of the walls cave in shortly before 11 a.m. Owner Charlie Gjerde said a wall on the side of the building collapsed into an alley. Painted bricks and tufts of insulation were heaped in the narrow alley where they fell during the chaos.
