I prefer forums like this for restaurant reviews. Most of the review threads offer plausible variability and a identifiable mean without the crazy outliers you can get with a single blog or something like yelp.
Also, I have to say that I get incredibly tired trying to strain the information out of blog posts like
"Wow! All I can say, is that the mouthgasm I got made me dizzy! And the spices were distinct and did a softshoe in my mouth(gasm)!"
