What you can eat here
Pulled from Gluto's celiac safety report for this location.
✅ Reported safe options
- Burger without a bun, served as a lettuce-wrapped burger or in a bowl.
- French fries prepared in a dedicated fryer (gluten-free in practice at this location).
- Note: No gluten-free buns are available at this location.
⚠️ Risks & cross-contamination
- The restaurant is not a dedicated gluten-free facility, so cross-contact risk can never be fully eliminated.
- While many diners report excellent precautions, there are occasional negative anecdotes about miscommunication or lapses, underscoring that safety still depends on consistent staff adherence.
- Peanut oil is used for frying in many outlets, which is a consideration for peanut allergies; for celiac safety, the gluten risk centers on buns and any toppings that could share equipment.
- No GF buns are available; the safest option is bunless burgers or lettuce-wrapped burgers with fries in a dedicated fryer, accompanied by careful glove changes and clear allergy communication.
