The Hamburger Wagon is a hamburger joint located on the sidewalk of the Market Square in Miamisburg , Ohio . The establishment was opened in 1913 by Sherman “ Cocky ” Porter to help feed residents of Miamisburg rebuilding from the Great Flood . The Hamburger Wagon is a small wagon , large enough for only two people to work side by side ; one cooks while the other one prepares the buns and handles the money . The wagon , still at approximately the same location where it originated , is rolled away and stored indoors nightly . The establishment has changed ownership hands several times throughout the years , most recently bought by Jack Sperry in September 2008 from Michelle Lyons . Unchanged , however , is the flagship product : small hamburgers cooked by oil in a large skillet and served on a roll with an onion , pickle , salt and pepper . The burgers have a crispness on the outside due to being deep fried
