The menu marks gluten-free items with a dedicated icon, and the chain's homepage says most of the selection is naturally gluten-free. Community reviews on FindMeGlutenFree report a dedicated fryer, a separate pasta pot, and knowledgeable staff, but also note that customisation for stricter diets may be limited outside peak hours. The kitchen is shared, so cross-contamination is possible. Call ahead if you're highly sensitive.
Honest caveat, Customisation for stricter diets may be limited outside peak hours; the chain advises letting them know in advance.
