How the scores work

Rating is each business’s live Google star average. Review volume is how many customers have rated it, compared across the businesses on this page. Confidence weighs the rating by that volume, so a 5.0 from a few dozen people counts for less than a 5.0 from hundreds. Recency tracks when the latest reviews were posted.
