The biggest feature of Qingquan Plaza is its dedication to maintaining the simplicity of when the old father first started the business. The menu offers affordable, high-value dishes with no minimum charge and no service fee. Additionally, they've thoughtfully designed a "parent-child playroom," allowing parents to enjoy a peaceful meal and a cup of tea while their children are entertained. This thoughtful approach fully reflects the original simplicity and warmth of the early days of the establishment.
