I think 3.5 stars is right on...
You've gotta love a one-city chain dedicated to that city's name sake - poutine.
I'm no poutine expert, being able to count my experiences on one hand, but I felt the poutine here was above average, but not amazing.
I'm still waiting to be blown away by poutine, but it wasn't here.... You will however have a consistent, affordable experience and they do have quite a good beer selection.
