What do you think US Senator Elizabeth Warren ordered when she visited Grass Fed this past weekend in Jamaica Plain? The answer: A grilled cheese and tomato sandwich with a root beer float, according to Boston Magazine, who spoke with store supervisor Ida Khojandpour. Warren is definitely familiar with the JP cuisine scene, having poured beers at Doyle's Cafe in 2012. More recently, Warren supported one of Massachusetts' most famous food favorites: Dunkin' Donuts. In June, she brought a bunch of donuts to the US House Democrats at the US Capitol during a sit-in protesting bills blocked by House leadership to expand background checks to prevent suspected terrorists from buying guns.
