Found it on this app, called in advance to check their safety measures. Even the server was very knowledgeable and satisfied us with their allergy precautions. The burger came in a box and separate from other orders, they also have a dedicated fryer for fries . Their poutine is Not gf . The only thing which they can improve is the bun, it fell apart, so may be a separate toaster to toast them well. Overall we were very happy.
The burger and fries tasted amazing but I am REALLY not feeling well this morning. We verified both were gluten free, but it's feeling cross contamination definitely occurred somewhere in the process. We did say gluten free, but maybe I should have emphasised that it kills me slowly
