Eating out with a dairy allergy
By the feefrae editorial team · Last reviewed 31 May 2026
Dairy ranges from a serious milk allergy to lactose intolerance, and what counts as “safe enough” differs hugely between them — which is exactly why a reassuring review from one shouldn’t be read as reassurance by the other. feefrae matches what you see to people managing dairy the way you do.
What matters when you eat out
- Whether dishes are genuinely dairy-free or just “can be made without cheese” — butter, cream and milk powder hide in sauces, breads and batters.
- Cross-contact on shared grills, fryers and utensils for a milk allergy (as opposed to an intolerance).
- Whether staff understand the difference between “dairy-free” and “lactose-free” — they aren’t the same thing.
- Written allergen information you can check rather than a verbal assurance.
Questions to ask the venue
The right questions — we hand you these, we never answer them for the venue.
- Is this dish genuinely dairy-free, including butter, cream and milk powder?
- Is there cross-contact with dairy on shared equipment?
- Do you have written allergen information for milk?
- Can the kitchen confirm with the chef for a milk allergy?
Frequently asked questions about eating out
What is the difference between a milk allergy and lactose intolerance?
A milk allergy is an immune reaction to milk protein and can be serious, sometimes from only a trace. Lactose intolerance is difficulty digesting milk sugar — uncomfortable, but not an allergic reaction. What counts as “fine” differs hugely between them, which is why a good report from one shouldn’t be read as reassurance by the other.
Is dairy-free the same as lactose-free?
No. Dairy-free means no milk-derived ingredients at all, including milk protein. Lactose-free means the lactose sugar has been removed but the milk proteins remain. Someone with a milk allergy reacts to the protein, so a lactose-free product is not necessarily suitable for them.
Is vegan food suitable for a milk allergy?
Vegan dishes contain no dairy by definition, which helps — but a vegan kitchen can still have cross-contact with milk, and “vegan” describes ingredients, not allergen handling. Many people managing a milk allergy still ask how the dish is prepared rather than relying on the vegan label alone.
What hidden dairy ingredients should I ask about?
Butter, cream, milk powder, whey, casein, ghee and milk solids hide in sauces, breads, batters, mashed potato, desserts and “buttery” finishes. A dish with no obvious cheese or milk can still contain dairy, so it is worth asking how it is made.
Is butter considered dairy?
Yes. Butter is made from milk and contains milk protein, so it is dairy and relevant to a milk allergy. “Cooked in butter” or “finished with butter” is worth asking about even when a dish has no other dairy in it.
Can a milk allergy react to cross-contact?
Yes. For a milk allergy — as opposed to lactose intolerance — traces transferred on shared grills, fryers, utensils or surfaces can be enough to cause a reaction. How separately the food is prepared matters, not just whether the recipe is dairy-free.
Should I ask for written allergen information?
Yes. Written allergen information lets you check for milk yourself rather than rely on a verbal “should be fine”. Under UK food law, venues must be able to provide allergen information for the 14 major allergens, milk included.
What should I ask a restaurant before ordering?
Whether the dish is genuinely dairy-free including butter, cream and milk powder; whether there is cross-contact with dairy on shared equipment; whether written allergen information for milk is available; and whether the kitchen can confirm with the chef for a milk allergy.

How feefrae gathers evidence
- feefrae collects reports from diners about how venues handled their allergy or intolerance, then counts and describes those outcomes. It does not issue ratings, scores or safety certifications.
- Reports are matched to your severity — a reassuring report from someone with lactose intolerance is never shown as reassurance for someone managing a serious milk allergy.
- Recent experience is weighted more heavily than old experience, because kitchens, chefs and suppliers change over time.
- feefrae never declares a venue a safety verdict and never tells you what you can eat. Editorial guidance like this page is decision-support, reviewed and dated by the feefrae editorial team — not medical advice.
