You need to apply for both the Catering Service Permit and the Hygiene Permit. The reason why you are required to apply for a catering service license instead of a hygiene license is because the person who asked you to apply for a license is from the Food and Drug Administration, not the Health Bureau, and they don't care whether you apply for a hygiene license or not. If you are asked to apply for a permit by the Health Bureau, you will be asked to apply for a Hygiene Permit, and they are too lazy to care whether you apply for a catering service permit or not. There must be a dining table in your cold drink shop. If there is no dining table, apply for a Food Circulation Permit. You need to go through the following procedures: 1. Catering service license 2. Business license 3. Hygiene license.
