I like eater.com and find it fairly reliable, but a bit more "hipster" than I'd like.
So many of the other sites that are more compilations of user reviews have become wastelands as many "reviewers" seem obsessed with getting their name in print as much as possible. Just last night I came across a bad review given to a restaurant that serves Italian food because the reviewer didn't like Italian food...not the restaurant's Italian food...all Italian food. Huh? This sort of stuff makes a quick look at star ratings and the like pointless.
