We went to Sky 360 for the Big Taste. It was on a Saturday for lunch and it was really quite busy. They offered both the Big Taste menu (their regular express lunch menu) and the regular menu. We chose the Big Taste menu - it is limited but you get an appetizer, main and free dessert. I had the salad to start which was good, but average. For my main I had the burger with fries, which was delicious. I loved the aged cheddar and pickled onion. For dessert, I had the pistachio torte, a yummy combination of red velvet cake, cream cheese mouse and pistachio brittle. It was light and a perfect end to my meal. As you are eating, the restaurant is revolving giving you a beautiful view of Calgary. I believe it rotates at 2 different speeds, but you can expect to do a couple of rotations during your meal (if you don't speed eat).
With your reservation, you don't have to pay to ascend the Calgary Tower, so after you eat, head to the observation deck and take another look at the city. There is also a glass floor for the brave.
