What you can eat here
Pulled from Gluto's celiac safety report for this location.
✅ Reported safe options
- Burgers on gluten-free buns (GF buns available; lettuce-bun substitution mentioned)
- Fries (gluten-free in multiple reports; some references to dedicated fryers)
- Gluten-free poutine (gluten-free gravy reported)
- Crispy chicken sandwich prepared with gluten-free breading (GF breading noted in at least one review)
⚠️ Risks & cross-contamination
- Facility status: The establishment is not described as a dedicated gluten-free facility. This means there is an inherent cross-contamination risk that diners should assess personally.
- Handwashing/food prep: One recent customer report described a moment during a very busy service where handwashing between buns wasn’t observed, followed by gastrointestinal discomfort. This highlights a potential safety lapse during peak times.
- Positive mitigations: Multiple guests report staff who are knowledgeable about gluten-free needs and who take care with GF buns, cleaning practices, or cross-contact considerations in regular operations.
