Unveiled earlier today, Google's new service, called Hotpot, promises to recommend places to you based on an extremely simple rating system that allows scoring and ranking establishments from one to five stars. Additionally, you can rate individual characteristics, such as food, service, and atomsphere, as you can see below. Hotpot's release was accompanied by a simultaneous refresh of the Google Maps Android app (version 4.7), which brought along the fairly significant addition of Hotpot to the Places component of the app.
I'm far too generous
Hotpot itself is accessible on any computer, but you'll obviously find rating and discovering places far more convenient while on the go.
