It's at 7 Ave,9 street,downtown.
It's also in SW.
You can take C-train in downtown(it's free),get off at 9 street station.
The building is on the north side of the road.
You'd better buy a calgary map,then you can find it.
I'm not good at English,but i found it when i walked in downtown.
Just have a try,don't worry.
