It's hard to say how this profit is, mainly depending on your own operating methods. If the location is good and the rent is expensive, then the profit will naturally not be as high as those shops with cheap rent. First of all, if the upfront cost is limited, please see the suggestions. You can choose a place with a good location but relatively cheap rent to reduce the rental cost. Then, the cost of raw materials can be directly wholesale in some vegetable markets in your city, so the wholesale price is naturally lower. Regarding whether it is troublesome or hard to do, what I want to say is that it is very troublesome and hard to do the catering industry. You have to get up early every day to buy raw materials in the vegetable market, because the food may not be fresh after you go, and it will also affect your business. Making original soup, soup base and so on are all very complicated procedures.
So doing anything is not so simple, but as long as you have perseverance, you can do everything well and make money!
I hope I can help you and adopt it.
