The score beside each business comes from a single ranking calculated on 21 August 2026. It has not been recalculated since, so it reflects the Google review data we held on that date, not today's.
That calculation is our launch method, and we are replacing it. A fuller explanation of how scores are produced will be published alongside the new method, and these pages will be re-ranked when it lands.
We could not tell 38 of these 40 businesses apart — they scored the same, and share a rank marked "=". Businesses on the same score are not ranked above or below each other. We had to list them in some order, so we put the one with the most Google reviews first; that order does not mean one is better.
