What you can eat here
Pulled from Gluto's celiac safety report for this location.
✅ Reported safe options
- Protein style burger (lettuce-wrapped) or Flying Dutchman (bunless two-patty cheeseburger)
- French fries prepared in a dedicated fryer
- Lettuce-wrapped burger variants (when bun is not used)
⚠️ Risks & cross-contamination
- Buns are the gluten-containing item; cross-contact risk exists if buns are handled near bunless orders or on common surfaces.
- Some toppings, sauces, or spreads have been noted as potential cross-contact sources; many guests mitigate this by using packets or avoiding spreads.
- In busy periods, mistakes can occur (e.g., shared tools or surfaces); the available allergen protocol emphasizes glove changes, dedicated prep areas, and separate packaging, but the allergen information letter cautions that complete elimination of exposure cannot be guaranteed.
- Onion preparation and other shared prep steps have been flagged in some reports as potential risk depending on location and staff workflow.
