As we plummet into the depths of Burger Week, the names of the classics will ring out: Nopa. Zuni. Marlowe. Joe's Cable Car. In-N-Out. But what about new burgers? They've never been a hotter menu addition, and seemingly every third restaurant to open its doors in SF and Oakland these days has one for your delectation. Herein, we offer 15 of the newest, hottest, and most critically acclaimed burgers on the SF circuit (with a couple of Oakland spots and a Larkspur holdout as well), all of which have sprung onto the scene in the past year. (They're listed in no particular order.) Which is your favorite? Any beloved new offerings that didn't make the cut? Sound off in the comments or on the tipline.
