Been here a couple times as they're right around the corner from my house.
The OMG / gardilly sauce is amazing and I can never have enough. I always get a little extra on the side.
Today I tried the Feast Poutine which is basically Thanksgiving as a poutine. It was definitely flavorful; my only complaint was I could have had more curds.
The gravy is vegan and the fries are gluten free for anyone wanting to try them.
This is a CASH only establishment, for anyone who hasn't been here previously.
