This is more for the East Vancouverite/other Vancouverites ie. just above this message of mine:
There's a Japanese supermarket about 1 km. from the old/historic Chinatown ...that Japanese-Canadians and other Asians frequent alot. They make a wide variety of competitively priced and fresh sushi and sashimi in takeout containers.
I go there to get best selection of their buckwheat noodles and also their green tea noodles.
Go ...where the Japanese in Vancouver go regularily.. http://www.fujiya.ca/vancouver_fujiya.cfm
We like buying their stuff and packing it into our panniers for a picnic by beach/park somewhere.
