The Best Place Score is the score we give to the place you're searching from, based on how cool we think the area around it is. If it seems unreasonably low, we probably just haven't added a representative amount of awards yet.
The Yumscore represents our confidence that you'll have a good experience getting something yummy. This raw score is based on awards it's won, and the score on a "Near Something" page represents the score, mixed with a proximity modifier.
The Stayscore represents our confidence that your stay will be an excellent one.
