What you can eat here
Pulled from Gluto's celiac safety report for this location.
✅ Reported safe options
- Protein Style burgers (lettuce-wrapped) for a gluten-free bun alternative.
- French fries (fries) prepared in a dedicated fryer.
- Milkshakes (gluten-free options reported by many diners; ask to confirm at your location).
- Flying Dutchman (two patties with cheese; can be ordered without bun and as protein style at times).
- Lettuce-wrapped variants of other burgers when requested and prepared with allergy precautions.
⚠️ Risks & cross-contamination
- Buns are the gluten-containing item; avoiding the bun by ordering protein style is common but requires careful kitchen coordination.
- Shared utensils and grills can pose cross-contamination risk; many staff stories emphasize glove changes, clean surfaces, and separate prep areas, but lapses have been reported.
- Some onion toppings (diced onions) may be grilled with the same utensils or surfaces as buns in some locations; requesting whole grilled onions or separate grilling can mitigate risk in some cases.
- No location is described as a dedicated gluten-free facility; ongoing communication and caution are essential to reduce cross-contact.
