Denny's
Denny's is a diner chain that publishes a national allergen guide for the contiguous United States, covering the FDA's top nine allergens plus gluten in separate ingredient and menu-item sections. The guide distinguishes items that contain an allergen from items that may contain it or are processed in a facility or on equipment with it. Denny's states the information comes from its ingredient suppliers and that the guide is updated periodically.

Questions diners ask about Denny's
Does Denny's publish an allergen menu or matrix?
Yes — Denny's publishes allergen material in pdf-matrix form, linked from this page and last checked on 2026-10-28. It addresses 10 of the 10 allergens we track.
Which allergens does Denny's's published material not cover?
It does not address: none — all 10 are addressed. Not addressed means the chain's document is silent on that allergen — not that the allergen is absent from the food.
If Denny's publishes a protocol, does every location follow it the same way?
A chain document is a ceiling, not a location guarantee. Locations vary in staff, equipment and practice, so a location listing on this site carries its own tier and its own last-checked date, and the questions on the visit-prep card are the ones to ask at the location you are visiting.
What does Denny's itself say about cross-contact?
Denny's states that, due to shared preparation and cooking areas in its kitchens and the risk of cross-contact, it cannot ensure that any item is free of any allergen.

Questions to ask at your location
- Is the fryer shared with breaded or battered items, and what else is cooked in that oil?
- Is there a separate prep area, boards and utensils for allergy orders?
- How are staff trained on food allergies, and how often is that training refreshed?
- Which parts of the kitchen, if any, are kept free of my allergen?
- Does this location follow the chain's published allergen procedure, and who here is trained on it?
ConfidentDiner collects allergen and preparation information from restaurants’ published materials, from restaurants themselves, and from diners. Information is dated and sourced, but menus, ingredients, suppliers, staff, and kitchen practices change without notice, and cross-contact can occur in any non-dedicated kitchen. Nothing on this site is medical advice or a guarantee that any restaurant or dish is safe for any individual. Always tell the restaurant about your allergy, confirm current practices directly before ordering, and make your own decision with your medical professional’s guidance.
