What you can eat here
Pulled from Gluto's celiac safety report for this location.
✅ Reported safe options
- Protein Style burgers (bunless lettuce-wrap) — explicitly used to avoid gluten-containing buns.
- French fries — typically cooked in a dedicated fryer, gluten-free by default.
- Gluten-free shakes — reported as gluten-free in the allergen information and reviews.
- Flying Dutchman (bunless, two patties with cheese in the middle) — widely mentioned by reviewers as a bunless option that can be prepared in a gluten-aware way.
- Note: No gluten-free bun option is offered at this location; cross-contact risks persist unless precautions are strictly followed.
- Request the order to be marked for a gluten allergy and prepared in a separated area with clean gloves and new utensils.
⚠️ Risks & cross-contamination
- Cross-contamination risk remains a consideration, especially since buns are the gluten source and grills/spatulas can be shared. Staff may change gloves and use separate surfaces, but practices can vary by location and shift.
- Some reviews mention that certain onion grilling practices or shared utensils can pose risks; others indicate that whole grilled onions or specific prep steps help reduce cc when allergy notes are clearly communicated.
- The restaurant’s allergen information emphasizes a “reasonable effort” to accommodate, but it also states that exposure to allergens cannot be guaranteed.
