The size of the US restaurant industry revenue in 2019 is "projected to total $863 billion in 2019 and equal 4 percent of the U.S. gross domestic product." [1]. Compared to $467 billion for the global software industry [2], or $19.1 for the global music industry [3].

I think there is some money to be made selling food.
