Plaza 1909, current status:
The second image shows the relationship between Plaza 1909 and the existing Swiss Chalet/Royal Bank/Second Cup development and the interconnected driveways (a smart idea)
The only confirmed tenants I know of so far for Plaza 1909 are Pita Pit and Papa John's Pizza. I imagine there are others.
One thing I really like about this section of Mountain Road between Gorge and Lonsdale is that you can now walk all the way from Second Cup to the Subway in Valhalla Place by crossing parking lots rather that takingn the sidewalk alongside (the busy) Mountain Road. It is certainly a lot more pleasant!
