The nostalgia play, conceived years ago when the world's richest man was still a Los Angeles hometown hero, bows in a radically different era.

When Elon Musk’s highly anticipated Tesla Diner opened its doors in Los Angeles on July 21, it garnered significant media attention, with customers lining up for hours to try chef Eric Greenspan’s pie shakes and classic burgers served in Cybertruck-shaped boxes. This past weekend, however, the lines looked a little different.

Elon Musk's Tesla-themed diner in Hollywood became the scene of an anti-Musk protest on Sunday. Protestors gathered outside the futuristic eatery with balloons resembling Musk that were animated to do Nazi salutes, in reference to a widely-criticized gesture that the tech billionaire made on President Donald Trump 's Inauguration Day.
