Hello, if you want to sell bento, you must first define bento, which means fast food. So who needs fast food? Students, workers, office workers and other crowded areas, such as railway stations and bus stations. I suggest you go to these places to do business! Next is the preparation materials: 1. Rice 2. Vegetables Meat 4. Egg 5. Cooking ingredients such as oil, salt, sauce and vinegar 6. Cooking utensils. Transportation (for purchasing raw materials and selling lunch boxes) 8. Tableware (chopsticks, napkins) 9. I suggest you prepare a few pickles, which will be included when you buy a box lunch. Careful service can win a good reputation and retain customers. If you cook by yourself, you will save the cost of hiring a chef. If you want to do business, you must make a field trip and make a practical plan. Others say it's better to practice by yourself. . . . Besides, if you are lazy, you can't join the service industry. I wish you a prosperous business!
