Not to mention the school cafeteria of the Earth era or Xilena First Affiliated School, even such a formidable institution like Xilena, their student cafeteria only serves nutritional meals, focusing on filling you up rather than taste, as long as you don't starve, that's enough. Moreover, many scientists now believe that nutritional compressed food is more scientific and beneficial for human health, so the school cafeteria pays even less attention to food taste.
However, the school isn't entirely heartless. If a student's family situation allows it, and you don't eat at the cafeteria but instead use a domestic robot to prepare food at home, that's also acceptable. But domestic robots aren't cheap, and not every student has the spare money to buy them for cooking. K3 and Lucy, however, didn't worry about this expense; what concerned them was that the robot's recorded recipes were too monotonous!
