What you can eat here
Pulled from Gluto's celiac safety report for this location.
✅ Reported safe options
- Protein Style burger (lettuce wrap instead of bun)
- Flying Dutchman (two patties with cheese, no bun; prepared as an alternative to bunless options)
- French fries (gluten-free when prepared in their dedicated fryer)
⚠️ Risks & cross-contamination
- Cross-contamination remains a theoretical and real possibility, especially if allergen handling isn’t strictly observed (glove changes, separate surfaces, and dedicated fryers).
- A minority of reports describe reactions or concerns about shared prep spaces, though these are outnumbered by accounts of careful handling when the allergy is clearly communicated.
- Because the menu does not include gluten-free buns, some people worry about other potential cross-contact points (e.g., sauces, spreads, or grilling onions). Many reviewers, however, note specific steps taken to mitigate risk when the allergy is stated.
