What you can eat here
Pulled from Gluto's celiac safety report for this location.
✅ Reported safe options
- Protein Style Burger (lettuce wrap) – burger without bun, commonly prepared with allergy precautions.
- Flying Dutchman (two patties with cheese, no bun) – widely suggested as a safer, bunless option by long-time diners.
- Fries – typically fried in a dedicated fryer, cited as gluten-free when proper precautions are followed.
⚠️ Risks & cross-contamination
- The restaurant is not a dedicated gluten-free facility, so there is an inherent cross-contamination risk, especially around grills and shared toppings.
- The official allergen information indicates a practical effort to accommodate allergies, but no facility-wide guarantee against cross-contact is provided.
- Real-world reports show that when allergy orders are clearly noted and precautions are followed (glove changes, separate prep areas, dedicated fryers, separate packaging), many diners avoid reactions. However, there are occasional accounts of lapses, particularly during busy times.
