Sumerians organized farmers in each city-state to build extensive irrigation systems of canals and dams under the leadership of priest-kings. The desert soon bloomed with an abundance of barley, dates, and other crops. Food stalls, a type of fast food establishment where pedestrians could order any type of food and be on their way with a fully cooked meal in minutes, were also found in Sumerian cities. Sumerians enjoyed beer and wine, and in their local taverns, they composed drinking songs.
