Griff’s Hamburgers, or Griff's Burger Bar, is a regional fast food chain founded in 1960 by Griff's of America, Inc. of Kansas City, Missouri, United States. At one time they had locations nationwide with the majority in the South near highway exits. Griff's was named for the founder, Harold Griffin. The restaurant buildings were of a patented A-frame design, produced by Valentine Diner of Wichita, Kansas. Later restaurants sported more conventional architecture. A bright yellow sign read HAMBURGERS in big block capitals. The restaurants offered both drive-thrus and patio dining.
