Other than necessary mechanical systems and bathrooms, the building's entire second story will be devoted to gallery space.[39] Arranged in four broad clusters around the building, each one of the twenty-six core galleries is designed in the form of a square or a rectangle at various scales.[40] Other services, among them the museum's education department, shop and three restaurants, will be at ground level, as will a 300-seat theater in the section of the building on the southern side of Wilshire Boulevard.[41]
