Like the steaks, Brandt hamburgers are 100 percent natural and made from animals that have fed on wholesome, sweet corn for over 300 days. The resulting flavor is extra lush and sweet. “We didn’t announce anything,” BRGR manager Marty Weil tells us. “It was a seamless change. But people love it! It’s a great product and we’re really happy with the switch.” In this highly competitive burger market, expect other restaurants to begin serving Brandt. But until then, BRGR’s got a nice little monopoly.
