Elon Musk opened a diner in Hollywood. What could go wrong? I went to find out

It was just before lunchtime on its third day of operation, and the line outside Elon Musk's new Tesla Diner in Hollywood already stretched to nearly 100 people. The restaurant has been billed as a "retro-futuristic" drive-in where you can grab a high-end burger and watch classic films on giant screens, all while charging your Tesla. After months of buildup and controversy, the diner had suddenly opened on Monday, at 4.20pm, the kind of stoner boy joke that Musk is well-known for. Hundreds of fans lined up to try burgers in Cybertruck-shaped boxes, or take photos of the Optimus robot serving popcorn on the roof deck of the gleaming circular diner. But that was for the grand opening.
