I was shocked to see the lukewarm industry response to calls for better labelling on menus following the latest tragedy arising from Byron Burger.

In several European countries allergen labelling on menus is mandatory - they use a letter code. DS is coeliac, and while it's not life threatening, if he accidentally eats gluten it makes him very ill. We find this menu labelling very clear & helpful, and most restaurants where we go are family-owned not changed, so it can't be that onerous.
I guess it's not an EU policy, or we'd have it here too, but I don't think it would be that hard to adopt.
Here, DS has to ask staff every time - unless items are identified as GF on the menu, which they are sometimes (like vegan & veggie).
