Super Duper Burgers

Super Duper Burgers was founded in 2010 in San Francisco's Castro neighborhood and has grown to multiple Bay Area locations while remaining 100% locally owned. The chain sources its beef exclusively from Brandt Farms — humanely raised and ground fresh daily — and uses organic cream from Straus Family Creamery for its shakes, with all packaging made 100% compostable as part of a commitment to sustainable, slow-food values.
