Pink Pearl for Dim Sum. It's on Hastings, east of Downtown. Great selection, expect a line. I think they'll put your name on the list for you if you call on your way in.
The Stock Market (or is it Stock Exchange?) in the Granville Island Public Market for soups and stocks. I bring home their fish stock in my luggage it's so good.
Not Roadfood, but my two favorite places in the city are Diva@The Met and Provence. Diva is nouvelle Canadian cuisine from a former captain of the Canadian Bocuse d'Or (sp?) team and one-time Iron Chef challenger. Have the black cod, anything involving duck, the Stilton cheesecake with walnuts and port wine reduction or anything with their raspberry sorbet with the unbelievable secret ingredient. Very tasteful dining room, great tasting menu.
Provence is provencal seafood and grilled things, mostly, with daubes and roasts making appearances from time to time. Great wine list, very personal service, neat small place (I like the one on 11th in Kitslano). I've not been to the other location.
Vancouver is a great food town, and the magic is that while the price on the menu is within a few bucks of Seattle menu prices (lower, usually), you're paying with Canadian dollars, so your dinner check is roughly 1/3 less than in Seattle - so it's affordable indulgence. I used to dine in Vancouver every other week with a standing dinner reservation at Diva I enjoyed it so much.
