The walls were painted in pastel pinks and greens straight out of that new cop show — Miami Vice.

The Cafe 80's was a nostalgic restaurant on the Courthouse Square in the year 2015 to remind the citizens of Hill Valley in the 1980s.

According to an early script for the movie, the Cafe 80's is owned by Biff's future son, Biff Tannen, Jr. »
