A 1931 Zig Zag Moderne petrol-station office, originally at Larkin and Pacific Streets, was moved to the corner of Beale and Howard in April 1990 and served as a food stand for about twenty-five years. SPUR's guide places the structure inside this building's own open space; San Francisco Heritage places it kitty-corner to the tower and records its removal in 2016 for a different office project. This page does not resolve which.
