I had lunch here yesterday and dined outdoor; great location for people and car watching with the lush green Mount Royal framing the backdrop!
I had the smoked combo meat. I ordered lean meat and with fries. I found the fries to be the best part of my meal! The smoke meat, despite being lean, still had lots of fat. The smoke meat was blend and didn't taste special -- actually, almost no flavor. It was C$17.
Well, I can cross off from my bucket list Dunn's, established since 1927.
IMHO, Schwartz's is much better with no pretensions and worth visiting again and dinning there -- it's a classic diner that looks like the original when it first open decades ago; even before I was born :)
