What exactly the War Room was is not directly revealed, though judging by its appearance it may have been a bar/nightclub.
Behind the scenes
- The elaborate set for Courthouse Square in the 1985A "Biffhorrific" timeline is visible on screen for only 60 seconds in Part II, between the time Marty steps across the flattened, bullet hole-riddled Hill Valley greeting sign, and notices the Biff Tannen Museum. Many of the details were not evident in the film, but a set of photos on the Blu-ray edition of the trilogy show what Lou's Café had become.
