BRGR Adopts Brandt Beef, Meat-lovers RejoiceBRGR does pretty good business in Chelsea, but wanna-be burger barons need to step up their game in this meat-manic town of ours. So BRGR, with little fanfare, has raised the caliber of its product, becoming the city’s first restaurant to adopt Brandt hamburger. Brandt is one of the most innovative beef producers in the country — their steaks already appear at Porter House New York, Craftsteak, and Park Avenue Autumn.
