Old Mill operates a dedicated 'flour free' menu, separate from the main menu, and also uses a dedicated gluten-free fryer, confirmed by multiple community reports and listings. Staff are described as knowledgeable and proactive. However, the kitchen is explicitly not 100% dedicated gluten-free, and the venue itself labels its offering as 'flour free / wheat free' rather than 'gluten free'. The venue's listing carries a standard non-dedicated disclaimer.
Honest caveat, At least one symptomatic coeliac reviewer reported a gluten reaction after eating the Irish stew, noting the menu is 'flour/wheat free' rather than strictly gluten-free.
