Time Out says
While it's primarily an office block, the Marunouchi Building (or ‘Marubiru’, as it's more commonly known), devotes its first four floors and basement to a shopping mall, while you'll find a range of restaurants on the fifth, sixth, 35th and 36th floors. The basement food hall is good for high-end gourmet products, and also contains branches of American Pharmacy and import grocery store Meidi-ya. Just across the street is the New Marunouchi Building, which opened in April 2007 and has a full nine floors given over to retail.
