The source pages identify cuisine and dining formats, not complete ingredient or allergen lists for the current service. Ask staff about the particular item you intend to order and tell them which ingredients must be avoided. A general label such as Chinese, Cantonese or international cannot verify that an individual plate meets a dietary requirement. None of these reviewed pages establishes halal certification, a gluten-free kitchen, vegan preparation or cross-contact controls, so this guide does not claim any of them.

The same care applies to traditional foods encountered elsewhere. Beijing's official food material describes zhajiangmian with a soybean-and-meat sauce, while many roast-duck presentations use pancakes, sweet bean sauce and accompaniments. A name familiar from a guide is not an ingredient certificate: individual kitchens and versions differ. For vegetarian or allergy-sensitive ordering, ask about sauce, stock, filling and preparation rather than relying on the short dish name. If the answer is uncertain, choose an item whose preparation can be explained clearly by the operator. (Beijing flavours, Roast-duck craft, checked 2026-09-29)
At Laoshe, clarify first whether the booking concerns the restaurant, tea service or a performance. Then ask Pinzhenlou what food is currently available and discuss ingredients for the exact meal. The official dining description does not contain a current complete item list. For an outside guest at any of the three hotels, dietary questions can be combined with access questions in one contact: identify the restaurant by name, explain the meal need and ask whether the dining room will admit non-residents at the intended time. This avoids both an unsupported menu promise and an unsupported assumption about entry. (Laoshe dining, Hotel dining example, checked 2026-09-29)
