Dunns used to be the place I would go when I first got to Montreal, but that slowly changed over time as I discovered much better places for smoked meat around the city such as the Main. Dunns has that interesting diner feel to it and it's located at the heart of the tourist area in Montreal.
Usually the service is alright here, but there have been a handful of times I've gotten service that is beyond terrible. I'm not talking they were slow or forgot to fill our drinks terrible. I'm talking they slammed drinks on the table, dropped food on our laps and acted like we were bothering them when we would do a simple thing like ordering.
On top of this the portions have gotten much smaller and the smoked meat just doesn't cut it compared to other places around town. This definitely is not a place I frequent anymore and it's mainly due to the staff.
