Although the Pacific Stock Exchange departed the premises several years ago, its spirit lives on in its namesake building's dark, dramatic, altogether spooky lobby. Designed by Timothy Pflueger in 1930, the foyer's high ceilings, Egyptian-Art Deco ziggurats, Oz-Expressionist ambience, and preponderance of black marble — it's like being inside the Banker's Heart statue in front of the Bank of America — make the lonesome wanderer long for a little rampant socialism. Luckily, Diego Rivera's Riches of California fresco can be found a mere 10 stories skyward in the City Club's stairwell, while Ralph Stackpole's massive worker-friendly Depression-era statues are right around the corner in front of what is now another yuppie fat farm.
