I have always had good experiences with Nando's, wherever I go. I have eaten in Nando's in Chelmsford, Lincoln, Nottingham and London. It's a reliable restaurant to have a good and safe meal. Meals come with a gluten free flag if you specify that it is an "allergy order" when ordering. They then ask what allergy and if you're coeliac. I have not ever felt ill after going and I usually have quite severe reactions to gluten, so I trust Nando's a lot now.
