A lot of people complain that high school cafeteria food is the worst, some complain that the good food is too expensive. So a good business idea would be a sort of fast food restaurant in the high school that would sell items like burgers, pizzas, etc. It could be like a Diner in the high school with indoor seating and a whole diner-like aesthetic. Good food at a relatively low price, good quality at a cheap price.
