There was a brief period where Foursquare based recommendations were good and drawn from your wider social graph. Now we’ve gone back to Yelp and Google Maps where reviews and ratings don’t mean anything. A lower than 4 star review on GMaps has netted me a cease-and-desist e-mail for defamation.
That puts personally curated travel docs and word of mouth back in play as Thrillist describes here.
