My boyfriend and I went here around 2:30PM on a Saturday. We knew we were at the right location because the line was out the door! However, the line didn't last more than 45 minutes, which was definitely worth it. We both got regular-sized orders of La Classique poutine. If you want to feel less greasy, I recommend ordering one to share (if there's just two people).
I expected the cheese curds to have more flavor, but overall it was as yummy as everyone says it is!
The restaurant is very cramped and everyone sits close together, but it makes for a fun experience.
