I was eating in a little restaurant when a lady demanded that the employees tell her what the ingredients were in an item she ordered. They informed her they didn't know because it was a "trade secret" and the parent company wouldn't even tell them. They gave her the corporate number, but she claimed "it's the law!" (this is in California) that if and when she asks they have to tell her. Is this true? Having worked in restaurants before, I was under the belief that a consumer can ask if a certain ingredient such as an allergen is in an item, but that ingredients do not have to be disclosed.
