The last few years, there was a teal coloured chip truck here. We tried it last summer, and wasn't too impressed. This year, it's a different truck. The woman running it was very friendly, it's a nice shady spot, but not enough seating considering how popular the spot is. There are plenty of benches though along the trail, just not practical for me and three kids.
She said the fries are fresh cut, so they take about 7 minutes. They did take longer.

Addition: We went back and tried a small poutine. I thought it would be the same size as a small fries, but it was much bigger, and too much for just Megan and I. The gravy was good, the cheese curds were plentiful, but I still wasn't keen on the fries themselves.
2016: We tried this truck again and I should have read my own review LOL. I think we got a small and it was more than enough for a post dinner snack. Again, the gravy was very good, the cheese curds were good, the service excellent (not fast though). We just aren't a huge fan of the naked fries. Don't let this deter you, as others report that they love the fries here.
This menu is from August 2017 but might still be relevant
