I don’t think I’ve met anyone in the UK who routinely checked tripadvisor for anything!
I just checked a few local restaurants to me in London that opened in the last few years, and the ratio of reviews is about 16:1 for google maps. It looks like stuff that’s been around longer has a much better ratio towards trip advisor though.
Almost certainly Instagram/tiktok are though. I know a few places which have been ruined by becoming TikTok tourist hotspots.
Not in the UK, but from Romania, I last checked Tripadvisor back in 2012, and that was for a holiday stay in the Greek islands. Google Maps has eaten the lunch of almost all of the entrants in this space, and I say that having worked for a local/Romanian "Google places"-type of company, back in 2010-2012 (after which Google Places came in, ~~stole~~ scrapped some of our data and some of our direct competitor's data and put us both out of that business).

Counterpoint: I have met people in the UK who's lives revolve around doing nothing but.
