By July 1958, the Seagram Building was already 90 percent rented. Tenants were willing to pay for space in the upper floors, compared to about for comparable new buildings. In its first year, the Seagram Building was expected to have about a 13 percent return on investment on its office space. Among the initial occupants were "a number of industrial and service corporations" that were involved in manufacturing, as well as Bethlehem Steel and Maruzen Oil. The building also housed Goodson-Todman Productions; the sales headquarters of Eagle Pencil; an industrial designer; a property manager; an art producer; a direct-mail advertising company; and various other commercial tenants. Restaurant Associates took ground-level space for the Four Seasons and Brasserie restaurants, which opened in 1959. Ultimately, the Seagram Building had 115 tenants for the luxuriously designed spaces, which were drawn partly because of Mies's international stature. By 1961, there was a waiting list for space in the Seagram Building.
