For those visiting Edmonton, Alberta, the first stop I recommend visiting is the Highlevel Diner. I used to live a block away from this local institution (going on 28 years now). They have the best weekend brunch - the cinnamon bun are the best.
The story of this diner is also quite interesting. The owner, Patrick Turner, had received quite a large bid from a developer to buy the site. They would have surely torn the restaurant down. Instead, Turner decided to sell the restaurant to the employees for half the value.
