The District has authorized 21 new food vendor carts in an attempt to diversify the city's street food offerings. Of those, 14 have settled on locations and, once they open for business, will sell a range of foods, including pizza, kebabs, soul food and Korean barbecue. In a spot check on Friday, only two -- a Korean barbecue cart and Delle & Campbell's Halal Luncheonette -- were operating so far.
