What you can eat here
Pulled from Gluto's celiac safety report for this location.
✅ Reported safe options
- Gluten-free sub on Schär bun (the most commonly used gluten-free option).
- Gluten-free bun is typically prepared separately, often on foil, and orders are sometimes labeled as gluten-free.
- The gluten-free bun can carry a small upcharge in some cases.
- Note: There is a publicly posted policy stating the gluten-free roll is available but the restaurant cannot guarantee a completely gluten-free environment in every location due to gluten-containing items in the same restaurant.
⚠️ Risks & cross-contamination
- The chain states that a completely gluten-free environment cannot be guaranteed at all locations because gluten can be present in other menu items.
- Stock variability: gluten-free bread can be unavailable at times, which may impact plans.
- Some toasting practices may involve shared equipment; certain diners prefer to avoid toasting gf bread to minimize cross-contact.
- While many reviewers report safe experiences, outcomes can vary by day and location, so it’s prudent to confirm current precautions when ordering.
