The compact, two-level store itself is entirely under the plaza, but is topped by a first-ever rectangular “penthouse” composed of four single panes of glass and a roof. Portions of the store are visible through the windows from the plaza level. The store’s two glass staircases are also visible through huge glass panes over the top of each stair run on the sides of the store. — ifoapplestore.com
