I had to post an enthusiastic "thumbs up!" for the Avenue Diner on 8th Ave. in Calgary. Had brunch and lunch there a couple of weeks ago (not on the same day ;-) and really enjoyed it. I can enthusiastically recommend the "Ultimate Fried Egg Sandwich", with aged cheddar, bacon and tomato, and the "Uptown Mac & Cheese" with Danish blue, roasted red peppers and basil.
Superb food, funky surroundings, and very friendly service. The next time I'm lucky enough to be in Calgary, you'll find me there for breakfast every day.
