From the FCS Book of Little-Known Facts – McDonald’s Restaurant

The fake McDonald’s restaurant in Los Angeles hiding in an office park used only for TV and commercial purposes

The idea is that it’s way too expensive to shut down a real McD’s for the day, so they shoot here. Not just US commercials, but they have signage and menu boards from all over the world.

-none of the tables are bolted to the ground. Everything can be moved around and repositioned for camera/lighting placement.

-there is no drop ceiling; it’s a grid for hanging lights/props/whatever.

-the wallpaper is magnetic. It can be changed to whatever they want it to look like in about 5 minutes.

-the warehouse contains an array of greenery (shrubs,trees, ect.) and fake snow. The look/feel of any season of the year can be achieved.
