Vancouver Yelp or UrbanSpoon or TripAdvisor
Yelp-super picky divas niggling over details and imagined slights or eager beavers trying to ingratiate into the community-functional illiterates galore make the place a howler for errors in grammar & syntax.
Trip Advisor-either starry eyed/moonstruck tourist newbies or perennial sore losers-little middle ground.
Urban Spoon-dimwits abound the Gimme Freebie Bloggie set-some of the most limited people imaginable and their dreary lives/execrable photography.
re: Sam Salmon
I use yelp the most. I do find that people complain over small slights too often and the ratings are not usually based on the food itself. Also too many overhyped hipster restaurants are rated highly which in fact are mediocre (ie Nuba).
I find tripadvisor to be quite good when I visit other cities (but you have to watch out for tourist traps)
I like Urbanspoon the least out of the three as it recommends mostly cheaper restaurants - but it does have some good recommendations that the other two sites miss sometimes.
