The District’s Department of Consumer and Regulatory Affairs reminds us that today is the last day to vote for your favorite food truck or cart as part of the 2010 Curbside Cookoff contest. The top 20 mobile food vendors, as voted by the public, will get the chance to ply their trade at the same time at CityCenterDC on October 7 and 8 in a display of the District’s reinvigorated love affair with cheap, but delicious food you get on the street. Register your vote until midnight tonight here.
