Ratings are diners’ own experience. They don’t make a dish safe; neither do we.

Where this comes from

Allergen answers come from the menu’s labels first, then the listed ingredients, then a model’s judgement checked when unsure. How allergen status is decided.

Questions about Flat Iron

Does Flat Iron have gluten-free options?

No dish is marked gluten free as served, from the menu read 10 Nov 2026. Each dish shows whether the venue labelled it or it was read from the ingredients.

Is Flat Iron coeliac friendly?

Eatcrush reads each venue’s own menu and says where every answer came from. It never calls a dish safe: kitchens share fryers, boards and flour, and menus change. If you have coeliac disease or an allergy, confirm with staff before you order.
