World's first hamburger....

The world's first hamburger fast-food is neither Mc Donald's nor Wendy's.It was White Castle, which began with a 15-by-10-foot concrete building in the shape of a miniature castle in Wichita, Kansa in 1921 by Walter Anderson and Waldo Ingram. It seated five customers at a time and the stream-cooked burgers cost only 5 cents each. Mc Donald's didn't open until 1948 in San Bernardino, California.
