"The Vienna Beef Factory was started by two Austrian-Hungarian immigrants, Emil Reichel and Samuel Ladany, who began selling their franks at the World’s Fair in Chicago in 1893. Now, Vienna Beef manufactures most of the actual hot dogs you’ll find at stands throughout Chicago. This means the hot dogs from its own little stand, across the street from its factory, have to be exactly right. And they are. If you want a hot dog done strictly by the rules, this should be your yardstick." - ByDennis Lee
