During my very recent trip to Montreal, we stopped at "Dunn's Famous" near The Bay department store on St Catherine. They are famous for their "smoked meat" which my girlfriend had but wasn't too impressed.
I had the 1/2 pound grilled cheeseburger. It was so good I was laughing! I enjoyed it so much that we went back a few days later.
Of all the very good meals I had while in Montreal, this is the one that made the biggest impression. I recomend it.
I wish I knew the name of the crepe and fondue restaurant in Old Montreal, we went there twice too. Very very good food.
If anyone can give a better location description, please post to this thread.
