This question is actually difficult to answer, because there are many luck factors in the catering industry, and there are many factors that affect your business, such as local taste, spending power, whether your position is suitable, competitors' situation, and the amount you can invest.

Therefore, how soon you can get your money back depends on whether you can effectively reduce your expenses in the early stage, such as whether you can negotiate the rent of shops, whether you can buy second-hand bargains for kitchen utensils and other equipment, and whether you can reduce your own labor costs. If you do all these things, and you can manage your family diligently, and gradually improve your taste and business strategy, you should be able to return to your capital in a year or so. If you find that the business is bleak after opening the store for 3-6 months, you should consider timely stop loss as soon as possible.
