How we ranked the best ramen in Castro (SF)
Every place on this list is scored by a Bayesian weighted formula combined with a volume bonus. It rewards consistent positive feedback at scale, not just a high average rating — a 4.9-star place with 12 reviews ranks below a 4.6-star place with 800.
score = (v / (v + m)) × R + (m / (v + m)) × C + γ × log₁₀(v)
The prior m adapts to each neighborhood: it's the median review count among local candidates. So 200 reviews counts as “small sample” in dense markets like the West Village, but “solid” in quieter neighborhoods. Places with extreme review volume that clearly dominate their peers are promoted to #1. No paid placements — every spot earns its position via the public data.
