How this list is ranked
Every place in our Castle Rock directory whose main category is sushi restaurants gets a score from its Google rating and review count, with Yelp weighed in where we have it, so a 4.8 with 600 reviews beats a 5.0 with three. A place needs at least a 4.0 Google rating and five reviews to be ranked, closed places are out, and a second location of the same name only counts once. Every spot earns its place on reviews alone. The ratings were last refreshed September 2026, and the order updates itself when they change.
