Professional explanation, if you want to include cold dishes, you must have a special cold dish room, which is very demanding. You must have a dressing room with a refrigerator, a cleaning cabinet and a special cold dish chef. If you can meet these requirements, you can make cold dishes. You can ask the relevant departments for details. For example, if you are a medium-sized hotel, you must go from the business license to the industrial and commercial, catering service license to the license of the health or drug supervision department, and start to do the details, so you will be in trouble in the future.
