While Dunn's smoked meat is definitely good - i really hate this particular location. The service is awful. The french fries are often cold. You're stuck either ordering a platter (which is way too much for lunch and given this location lunch is their main meal) or a sandwich without the fries/coleslaw/pickle.
Why are onion rings over $6? I want a SMALL portion with my sandwich. It's really nice that you leave the ketchup and mustard bottles on the table, i have to ask for mayonnaise (and we're in Quebec - this is pretty standard) and the mustard is cheap.
So - have Dunn's at another location where the service is better.
Wait, go to Schwartz's.
