食べログスター拡張 is a Chrome add-on developed by muranet. It is a free tool that enhances the user experience on Tabelog, a popular food and restaurant information website in Japan.

On Tabelog, each restaurant's page displays a rating score in the form of stars. However, these scores are based on Tabelog's own weighting system, which can sometimes result in lower ratings for new or less-reviewed establishments.

食べログスター拡張 addresses this issue by adding the "average user review score" below the star ratings on Tabelog. This additional information provides a more accurate reflection of user opinions, allowing users to discover high-rated restaurants even if they have lower Tabelog scores.

With 食べログスター拡張, users can make more informed decisions when choosing a restaurant, ensuring that they find establishments that align with their preferences and tastes.
