We ate here to try poutine, and the whole place was nothing special. The ice tea tasted like concentrate, the waiter was friendly but not over attentive.
Poutine was o.k., the fries were great and crispy and tasteful, but were unfortunately soaked by the watery-greasy gravy.
We went again the next day, our new waiter was very nice and helpful, burgers were great and I could really enjoy the great fries! As we wanted to have desert, we were advised very well and even told which ones come frozen and which are freshly made (the first time I experienced this, left me stunned and slightly incredulous it actually happened). We chose to share a fresh apple pie and it was amazing! So turns out poutine is just not my thing, yet I can totally recommend Dunn's!
