The business, may require a food service permit (unless they are selling packaged food) in addition to a business license, too, in combination with food handler's permit for workers. At least, that's the case for the county where I live. (King County, WA) In fact, places like Trader Joe's (where they don't sell, but merely give away food sample) require an appropriate license to do that, too. They are also inspected fairly routinely, and every couple does get shut down for incompliance (problem with temperature, separation of raw meat, etc.) and I can see why these would require a license in order to prevent food-borne illness.
