Grassfed Marin Sun Farms chuck is ground in-house to produce this well-balanced burger on grilled brioche. Don't leave the pickled red onions on the side; they're the perfect topping.
San Francisco is known for a number of foods -- cioppino, sourdough bread, Rice-a-Roni -- but in 2011, there's no food more popular here than the once-humble hamburger. Practically every upscale restaurant has a burger these days; the offerings have never been better. We chewed a lot of grass-fed beef to bring you our list of the Top 25 Burgers in San Francisco (which are not ranked in order). Hope you enjoy looking at them as much as we enjoyed eating them.
