How ColaSnob ratings work
Every score is crowdsourced: visitors rate the Diet Coke 1–5, and we show a Bayesian average that gently pulls spots with only a few ratings toward the overall mean — so one or two reviews can't dominate. A location's availability changes only when several independent people agree, never on a single report. More in the FAQ.
