I was going to mention that, most of Stanley Park as well, same with any where along the waterfront of Coal Harbour.
Most of the pedestrian only areas in Japan are also parks, or they are mall style walkways with proper canopies, or they are outside walkways that are simply far to thin for cars.
In fact, it is very common in Japan in a pedestrian area to still have taxis and service vehicles honk their way through.
In a way it makes for a more busy and fun atmosphere.
But there is a lot vancouver can learn from East Asia (night markets under the shelter of the viaducts is one...)
I still think the best streets in Vancouver to be Pedestrian only are Granville and Hamilton. I am always surprised that Hamilton is never listed as a potential street for pedestrians only. During the Olympics it was so much fun with venders, live music, etc... and with the Yaletown station right beside it, and all of the restaurants, it is perfect!
Robson on the other hand is more of a Cosmopolitan street, and actually works better with traffic, again giving it more of a strip vibe.
