Today, the cliff and the stair have been replaced by a gently tiered outdoor plaza that provides a much-easier transition between street level and the riverfront. (An elevator inside the store will provide access to those in wheelchairs.) In addition, the stairs form an amphitheater like those on Chicago's riverwalk. Now it's up to Apple to book concerts and other programs lest the space become as dull as the river-level plaza at the nearby Trump International Hotel & Tower.
