This place is pretty cut and dry. They have about 8 options which are all derivatives of the same poutine. You order, wait a few minutes and it's ready. There's not much space to dine in. They maybe have 4 stools max, so you should definitely come prepared to either walk out with your food and eat on the sidewalk, as most people tend to do or, have them wrap it up to go. Based on the use of what appears to be blue masking tape to secure the container when you ask for it "to go", I am convinced that many people don't bother with this option.
We tried the original and the bacon (with the maple syrup). They were both good. Granted this was my first time having poutine and based on the description, I was anticipating something kinda gross, but worth trying once. My expectations were certainly exceeded and I would try it again. Not true preference between the 2 options I tried. They also had chicken and vegan options, so there is something for everyone.
They come in 2 sizes: tiny and regular. Don't let the terms confuse you. It's kind of heavy so a "tiny" was sufficient for me. The prices are also very reasonable.
