Restaurant Chaininess

This map shows restaurants marked by their CHAININESS: a metric that represents the number of other restaurants/cafes that share a name. For instance, Old Ebbitt Grill is labeled 1 since it is the only restaurant in the 48-U.S. states with that name. Subway and McDonald’s have a CHAININESS of over 10,000.

What am I looking at? The red dots on the map are chain restaurants. The yellow dots are independent restaurants. We cannot disclose the exact names at this time–check back later this summer for an updated map app with restaurant names.
