We've been polling all week for your favorite burgers in four different categories—chains, fast-casual, gourmet and wild card burgers—and we're pleased to announce that we have four strong contenders remaining for Best Burger in DC. From the burger chains, we've got Five Guys, and Good Stuff Eatery is representing fast-casual. BLT Steak was your choice for best gourmet burger and the wild card winner was Matchbox with its famous sliders. Now's the time to cast your vote for the citywide winner, and choose carefully: DC's best will go on to represent our fair city in a national face-off against our other Eater cities to crown the country's best burger. Polls close at 11am tomorrow, with the contest immediately moving to Eater National.
