Surprise! Today we're not just voting on best gourmet burger in DC—we're also polling on the city's best wild card burgers. And this category is wild indeed. We've got those famous Matchbox sliders, EatBar's beloved burger and the Westend Bistro's fish burger competing for the fourth and final slot in the Best Burger in DC finals. The winner of that will go on to Eater National to find out, truly, who is the greatest burger of them all.
