Take a tour of 5 Fun Facts About Hamburgers in Phoenix, United States - part of the World's Greatest Attractions travel video series by GeoBeats. Hamburgers are made of beef, not ham, and there is much debate over whether they actually originated in Hamburg. However, the hamburger in its current form, with ground beef and a bun, is a decidedly American creation. The largest hamburger ever created was over 8,000 pounds and was cooked for a burger festival in Wisconsin. The people of America eat more burgers out at restaurants or on the go than they do at home. The oldest fast food restaurant in the world is the White Castle franchise, which opened in 1921.
