Whack-a-drone

In Pasadena, California, there's a cute red brick courtyard where one storefront isn't like the rest. The glass doors open onto a sparse industrial hallway, which leads to a sunlit foyer with a large spiral staircase.

Go up, and you'll see a typical coworking space: open tables, healthy snacks, a collection of meeting rooms with glass walls. Follow one hallway most of the way back, and you'll find Office 18.
