As long as you eat it most often, as long as it is delicious and affordable, are you afraid that no one will eat it? Looking back on that year, I remember eating ordinary rice and vegetables at a window for a semester. But I think the taste is ok. If you have a better attitude, you will definitely make money by selling more.
It is also possible to set up some single rooms for students who celebrate their birthdays, and the potential market is still good.
