⚠️ Risks & cross-contamination
- The restaurant states it is not a dedicated gluten-free facility, and there is no guarantee that food will not touch gluten or be prepared near gluten-containing items.
- A negative experience was reported by at least one guest several years ago, highlighting variability in safety depending on staff and communication.
- While recent staff seems knowledgeable and GF options are there, the risk of cross-contamination remains and should be managed by clear server communication and choosing clearly labeled GF items.
