⚠️ Risks & cross-contamination
- Not a dedicated gluten-free facility, which inherently increases cross-contamination risk.
- Some reports mention gluten-containing components in common sushi ingredients (e.g., rice vinegar) or sauces; substitutions and verification are needed.
- Allergen labeling on the menu is noted, but a few diners still felt uncertain and recommended double-checking with staff for each dish.
- Recent experiences are mixed: some guests had positive results with gf options, others noted price and potential gluten risks.
