Bite into any Super Duper burger, and taste the difference. Our burgers, fries, and shakes are made with the finest, freshest ingredients available.

All our beef is Brandt Farms, humanly-raised, 100% vegetarian-fed, ground fresh daily, and sourced from a family-owned ranch.

All of our shakes and cones are made with organic cream from Straus Family Creamery, a small, family-owned, organic farm located on the pastoral shores of Tomales Bay.

Our buns are baked to our specification by an artisan baker in San Francisco.

The potatoes we use to make our French fries are made from potatoes grown in North America by growers who are required to identify the genetic source of their seed potatoes. We do not work with genetically modified potato varieties. Our potatoes are processed fresh off the field and delivered to us without any modifications. We proudly serve Sir Kensington ketchup.
