⚠️ Risks & cross-contamination
- There is no explicit claim of a dedicated gluten-free facility.
- A recent guest indicated GF staff knowledge and separate storage for GF cupcakes, which suggests cross-contamination precautions are considered, but absolute prevention cannot be confirmed from the collected information.
- While the nut-free status lowers some allergy risks, celiac safety still hinges on gluten handling in shared facilities; this remains a potential risk area given the available evidence.
