If it is not affected by the financial turmoil, but changes brought about by repeated competition, it is suggested to find out the most important effective customer groups in the past (that is, to make money from them) from the current dishes. Then repair this customer base and completely update the menu style of fast food restaurants!
It is not recommended to change the business direction prematurely. After all, the cost of changing from western fast food is too high. Try to avoid hurting bones and muscles. Maybe it's a good idea to start with western food and strive for perfection.
