Actually OP found a very small correlation between railway proximity and Google rating. The study didn't actually measure "quality"...

Also, the lowest scoring outliers were the closest proximity, which I think is noteworthy.

And probably understandable. Empirically, I don't really expect to find the best restaurants right around railway stations.

Yeah. The overall correlation was tiny but just looking at it you could see a pattern that's getting lost in the analysis.
