What you can eat here
Pulled from Gluto's celiac safety report for this location.
✅ Reported safe options
- Lettuce-wrapped burgers
- Burgers served in a bowl
- French fries prepared in a dedicated fryer
⚠️ Risks & cross-contamination
- The restaurant is not a dedicated gluten-free facility, so cross-contact risk exists in theory.
- There is variability in staff training across locations and experiences; while many recent visits highlight strong allergy protocols (glove changes, separate prep, allergy shouting, and separate packaging), there are occasional reports of gaps or confusion at some times/locations.
- Milkshake ingredients and some toppings may contain gluten, depending on flavor or ingredient, so it’s wise to confirm specific items beyond burgers and fries.
- Peanut oil is used for frying in many Five Guys locations, which can be a concern for peanut allergies. Diners with peanut allergies should consider this alongside celiac-safe fry options.
