What you can eat here
Pulled from Gluto's celiac safety report for this location.
✅ Reported safe options
- Burgers with gluten-free buns (Udi’s buns) when requested.
- Fries and/or tots prepared in a dedicated gluten-free fryer.
⚠️ Risks & cross-contamination
- This Smashburger is not branded as a dedicated gluten-free facility. Cross-contamination risk exists, as with many chain environments.
- While many guests report effective precautions (gloves changed, separate prep areas, dedicated fryers), there are historical notes of risk in the broader reviews and a few negative anecdotes from years past. Recent evidence heavily favors safety when you communicate clearly with staff and rely on known precautions.
- In practice, some fry items have been noted as potentially sharing a fryer (hot fries vs. certain sides); asking for specifics at the moment of order is a wise step.
