Seth explores plant-based cuisine in the DC area. His first stop is to Dupont Circle to visit DC Vegan and try their twist on an old favorite: the jackfruit Philly cheesesteak. He then heads to Chay in Falls Church to try the hearty vegan take on the Vietnamese bun bo hue. And finally, he samples a savory mushroom kitfo, along with bold Ethiopian coffee, at Feru Restaurant & Bar.
