Too far from the Rockies to see anything of significance
and Calgary's downtown is not the most impressive.
I did it because I had an hour or two to kill.
Pretty underwhelming.
I then found you get free admission to the tower if you eat at the restaurant, though it's not advertised anywhere.
I wanted to eat at the restaurant that revolves (their menu looked good),
but you have to book it in advance, no walk-ins.
Not worth the $17, I was in and out in under 20 minutes.
