Show HN: CheapFoodMap crowdsources verified sub-$10 meals across US cities

CheapFoodMap is an indie web project that plots inexpensive meals—diner specials, taco spots, sandwich shops, and other ‘hidden gems’—on an interactive map, with every listing priced at $10 or less. Coverage skews toward major metros, with the densest catalogs in Houston (66 spots), Philadelphia (59), Chicago (57), Seattle (47), and San Francisco (46), and thinner coverage in cities like Dallas and Brooklyn.

Each entry pairs a specific dish with a restaurant, location, and price, and carries a ‘price verified’ date—all sampled entries were verified the day of posting—suggesting the project tracks freshness rather than relying on stale user submissions. Sample listings range from a $1.50 Costco hot dog to an $8.99 crispy chicken wrap combo, spanning fast food, ethnic eateries, and sit-down specials.

As a Show HN launch, this is a consumer-facing side project rather than a security or infrastructure story. Its main technical interest lies in the data problem it tackles: keeping a geographically distributed, price-sensitive dataset accurate over time, where menu prices drift and verification quickly goes out of date.
