What you can eat here
Pulled from Gluto's celiac safety report for this location.
✅ Reported safe options
- Short rib GF pasta
- Prosciutto GF crust flatbread
- Kobe burger with a GF bun
- GF margarita flatbread
- Fries that can be made gluten-free if requested
⚠️ Risks & cross-contamination
- There is no dedicated gluten-free facility, kitchen space, or fryer.
- Some items (e.g., flatbreads) are prepared in shared ovens; gloves and prep practices may be adjusted upon request.
- Staff may explain the risk of cross-contamination and, at times, indicate that safety cannot be guaranteed.
- While several GF options exist and have been enjoyed by diners without adverse reactions, the absence of a dedicated facility means there is inherent cross-contact risk for people with celiac disease.
