What do you ask a restaurant? Eight questions that make the difference

“Do you have anything gluten-free?” is the question that yields least: almost every kitchen says yes. These eight questions are about preparation, and a kitchen cannot answer those on autopilot. The answer tells you more than the menu.

In short
Call ahead and outside service; at the table at half seven it is too late to arrange anything. Name coeliac disease as a medical condition, not as a dietary preference. Ask about preparation, and ask explicitly what they cannot guarantee.

Call ahead, and call at the right moment

A kitchen can arrange a lot when it knows: a clean pan, fresh oil, bread toasted separately. That only works if the question does not arrive in the middle of service. So call in the afternoon, between shifts.

Start with what it is. “I have coeliac disease, an autoimmune condition — even crumbs are a problem for me” gives a kitchen more direction than “I eat gluten-free”, because in hospitality the latter can also mean a preference.

The eight questions

You do not have to ask all of them. The first three cover most of the risk; use the rest where they apply.

  1. Can the kitchen cook gluten-free, or do you have dishes that happen to contain no gluten? This is the core question, and the distinction is exactly where things go wrong.
  2. Do you have a separate fryer for gluten-free? If not, chips and anything deep-fried are out.
  3. Will a clean pan and fresh cooking water be used? Relevant for pasta, rice, gnocchi and anything boiled.
  4. Where is gluten-free bread toasted? A shared toaster is one of the most-missed sources of contamination.
  5. What is the sauce or gravy thickened with? Flour is the standard answer; cornflour or a reduction is good news.
  6. Is flour being worked in the kitchen right now? In a pizzeria, a bakery or a kitchen making dough, flour is in the air.
  7. Will it go on the ticket as an allergy, and who plates it? That tells you whether the message reaches the kitchen and the pass.
  8. What can you not guarantee? The most important of the eight — and the most honest answer a kitchen can give.

How to read the answer

You hear the difference in the shape of the answer, not in how friendly it is.

This sounds right
  • “Let me check with the kitchen.”
  • “We have a separate fryer, but we do bake bread in the same room.”
  • “The chef will come by in a moment.”
  • “We can do that if you mention it when booking.”
This is a reason to keep asking
“Everything here can be gluten-free”, “we will take the croutons off”, “surely a little is fine?”, or a yes that arrives before the question is finished. None of those answers is in bad faith; they only show that the distinction between ingredient and preparation has not been made yet.

At the table, and afterwards

Repeat it when you order, even if you called ahead — the shift that picked up the phone is often not the shift serving you. Do not ask for a guarantee, ask for a description: “how is this prepared?” always yields more than “is this safe?”.

And if it went well: leave it behind. A review from someone with coeliac disease weighs heaviest in the gluten score, and it is the only signal that tells the next visitor this kitchen genuinely understands.

Frequently asked questions

The questions people ask most about this.

Do I have to say I have coeliac disease?

It helps, because the difference between a medical condition and a dietary preference determines how much trouble a kitchen goes to. You do not have to tell them anything else about your health beyond the fact that crumbs are a problem.

What if they will not give a guarantee?

That is often the answer of a kitchen taking it seriously — nobody can give a guarantee. Ask on about what they do keep separate, and decide on that.

Is it not rude to keep asking?

No, and most chefs prefer it to a surprise during service. Asking between shifts rather than during the rush is the difference between asking and interrupting.

Can I do this by email?

Yes, and with a booking that is handy because it stays attached to your reservation. Do call if you get no reply: a mailbox is not a kitchen.

No guarantee, but something to hold on to
This article gives you something to work with, not a guarantee: only the kitchen itself knows how it is working tonight. For medical questions about coeliac disease, or about what you can tolerate, see your doctor or dietitian — that is not ours to answer.

Eaten somewhere good? Add it

What the kitchen did, what was kept separate and how it went — that is exactly what the next visitor with coeliac disease needs.
