What you can eat here
Pulled from Gluto's celiac safety report for this location.
✅ Reported safe options
- Protein Style burgers (lettuce-wrapped, bunless) when you have a gluten allergy
- Flying Dutchman (bun-free burger option)
- French fries prepared in a dedicated fryer
- Milkshakes (gluten-free options, as commonly reported by guests and allergen materials)
⚠️ Risks & cross-contamination
- Cross-contact risk exists in any busy kitchen, especially where buns and patties share equipment or utensils. There are multiple reports over the years of cross-contact incidents at various locations.
- To minimize risk, guests are advised to: clearly state gluten allergy at order, request glove changes, request separate prep areas and utensils, and opt for lettuce-wrapped burgers (protein style) with fries in a dedicated fryer. Some reviews emphasize asking for items to be bagged separately or noted as allergy orders on the receipt.
- The presence of buns as the gluten-containing item is the primary, consistent risk factor; all safe options avoid buns and use separate preparation lines when possible.
