One food business license can only open one Racer Food Store. According to the Food Safety Law and relevant administrative regulations, food operators engaged in food service must obtain a food business license in accordance with the law, and indicate the business premises and business items on the business license. Therefore, a food business license can only be used for one business premises and cannot be used to open multiple Racer Food Stores at the same time. If a food business operator wants to open more than one fast food store, he must apply for a separate food business license for each store and indicate the corresponding business premises and business items on each business license. It should be noted that food operators who open multiple fast food stores in the same business premises are also required to apply for separate business licenses and indicate different business items. Otherwise, it will be suspected of violating the relevant laws and regulations, and be penalized by the relevant departments.
