FrontierSushi in San Francisco

The 10 highest-rated sushi places in the committed San Francisco pack, ordered by each listing's own Google Places rating — listings with fewer than 20 ratings are not ranked, and equal ratings break toward the larger sample. This is pack-wide standing, not the map's drive-time order; open a place for its report, or jump straight to it on the live frontier.

A listing joins FrontierSushi when its name mentions “sushi”, or its Google type is Sushi Restaurant. Matches come only from each listing's own name and Google Places type tags — cuisine alone is never inferred.

Sushi places are identified by listing name plus the Google “Sushi Restaurant” type — a Japanese or seafood restaurant serving sushi without either marker is not counted, so this frontier is a lower bound.

Counts are listings inside each committed pack — a coverage sample, not a popularity or quality ranking. The mapped regions overlap (the Bay Area pack includes San Francisco) and cover only crawled Google Places listings, so they are not comparable measures of a region's food scene.

Counts are Google Places (New) listings from each region's committed crawl data; a place joins a frontier when its listing name or Google type matches that category. The pack build date shown is when the routing pack was compiled — the original crawl collection dates are not recorded, so listing freshness is unknown. Drive times on the map are free-flow estimates — road-class speeds, no traffic, no parking, no queue at the counter — computed only out to a two-hour limit; beyond that a place is simply uncharted. Quality scores are ratings scaled to 100 — a rating-derived proxy, not a taste measurement. Unrated places cannot be charted.

Only places whose Google listing says “Halal Restaurant” or whose name contains “halal”. Cuisine alone is never treated as certification — many halal kitchens are missing here, and listed status is unverified.

The full pipeline — corpus, road graph, speed model, routing and ranking — is documented on the methodology page.
