Inspired by an awesome taste-test of national fast-food burgers written by... ourselves!... we decided to do a local SF version, where -- instead of eating a bunch of In-N-Out cheeseburgers (wait... why didn't we do that??) -- we decided to taste-test all of San Francisco's local "chain" burgers, i.e. signature burgers available at restaurants with more than one location.
Our rules were pretty simple: 1) The burger had to be available at multiple locations in San Francisco, meaning there's a good chance you can either get it by your house, your work, or your Tinder date's apartment, 2) we could only have the signature burger as-is, no modifications, 3) we had to eat them all in one day, and 4) no national fast-food joints. Seven burgers later, here're our definitive "chain" burger rankings.
