I think Google has just recently reached a "good enough" state for Yelp like use-cases, while Yelp has simultaneously declined, that I'm nowadays more likely to just use Google.
I don't use yelp anymore, all the places around me google reviews seems to become more and more popular. Instantly I get nice photos, hours, directions, and just as quality of reviews. The best thing, sometimes a direct link to the menu. Show times are much better than going to fandango etc. I want to spend less time on my phone navigating sites and more time giving options to my wife or friend who's traveling with me
