Yelp data and statistical sampling was used to determine that the average restaurant is better on Manhattan streets than avenues, with an average rating of 3.62 on streets vs 3.49 on avenues. The difference was statistically significant. In addition, you are almost 50% more likely to find an outstanding restaurant while on a street compared to when you are on an avenue. 18% of restaurants on the streets had a score of 4.5 or higher, compared to 13% of restaurants on avenues.
