Totally agree. Michelin guide is the only reliable option.Not particularly great results for me, but then I wouldn't use google maps to start with.
Tangentially related to this is the London Reddit Angus Steakhouse story. A bunch of people complained that all their favourite places to eat would be put on instagram, and then be ruined as a result. They concluded that the only solution was to try to promote Angus Steakhouse and hope that this would be picked up by visitors leaving their favourite places untarnished. They then went on a relentless campaign of always posting how great Angus Steakhouse is. Comically, Angus Steakhouse picked up on it and started using it in their marketing "Best steak sandwich as voted by Londoners".
For those unfamiliar with Angus Steakhouse - it is not somewhere you would choose to eat.
