For food, I've enjoyed Foursquare for a better signal:noise ratio in reviews. I am generally quite satisfied eating at its top-reviewed places for any given search term. Coverage of locations is almost as good as Yelp although you'll miss a few restaurants here and there (I'm in NYC).

Just be sure to turn off the always-on location tracking and go through the other privacy settings.

I typically cross-reference Foursquare with Google Maps reviews to make sure the overall rating is similar, since I'm a stickler like that.
