1: Find out whether the rented space is within the jurisdiction of the school;
2. Look at the second question you asked, knowing that you should not have been engaged in the catering industry all the time. When you ask what equipment you need, you have pots and pans, a chopping board (panel) and raw materials for cooking every day. As for how much food and equipment to buy, it depends on how many people you can serve and how many people will buy your food.
As for beer and drinks, you can find several shops near the school and ask them their phone numbers (they usually leave their phone numbers in the shops). If you are looking for a bigger beverage supplier, you can settle accounts on a monthly or quarterly basis. There is no need for a second knot.
3: 60 square shops, big and small. If they open a shop near the school, they can take it home to eat without providing more space.
4. About the handling of documents:
Food hygiene license, fire safety license, environmental protection license (hereinafter referred to as environmental protection, this license is the most difficult now), industrial and commercial business license. We need four catering certificates here now. I don't know how you are there. If you can't get one of the three certificates of food hygiene, fire safety and environmental protection, then you can't get a business license. You have to go to the industrial and commercial office to get a form, fill it out and have it stamped before you can apply for other permits. Some schools also provide unified management.
Wish you success!
