What you can eat here
Pulled from Gluto's celiac safety report for this location.
✅ Reported safe options
- Protein style burgers (lettuce-wrapped, bunless)
- French fries, cooked in a dedicated fryer
- Gluten-free shakes (noted as safe in several sources)
- Flying Dutchman (two patties with cheese, no bun)
- Other items can be made gluten-free if prepared with strict allergy steps and separate prep, but buns are the gluten-containing item and thus not safe by themselves
⚠️ Risks & cross-contamination
- The facility is not dedicated gluten-free, so cross-contact is possible in some prep areas and on shared equipment.
- Buns contain gluten and are the primary risk item; anything involving bun-associated preparation should be avoided for strict safety.
- Some reviews mention onions and other toppings being prepared on the same grill or with shared utensils as buns, which can cause cross-contact if not managed carefully.
- The allergen information document indicates that some items are produced in facilities where other allergens are present, and not all ingredients are guaranteed gluten-free in every context. Staff training and consistent adherence to allergy protocols are essential to safety.
