What you can eat here
Pulled from Gluto's celiac safety report for this location.
✅ Reported safe options
- Protein-style burgers (lettuce-wrapped) to avoid buns (explicitly supported by many diners and referenced in the collected evidence).
- French fries prepared in a dedicated fryer (frequently cited as gluten-free and separate from bun-related surfaces).
- Flying Dutchman (bunless two-patty option) as a gluten-free alternative that avoids buns.
- Optional side items or add-ons that are commonly discussed as safe when prepared with allergy-noted precautions (e.g., sauces or spreads requested in packets to minimize cross-contact).
⚠️ Risks & cross-contamination
- Buns contain gluten; cross-contact risk is present if buns and patties share grills, utensils, or surfaces not properly cleaned.
- Onions and toppings can be prepared with shared tools in some setups; some staff will arrange separate grills or dedicated utensils when alerted to an allergy, but this can vary by location and busyness.
- While many reviewers report safe experiences, there are isolated accounts of cross-contact or reactions at other locations or times, highlighting that results can depend on staff workflow and adherence at that moment.
- The official allergen document explicitly states that exposure to allergens cannot be guaranteed, reinforcing the need for careful ordering and diligence.
