Chinese street food that I wish could be found in the US
During this time of year in northern China, I sometimes was able to buy roasted sweet potatoes sold on the street by vendors using steel barrels to cook them. Most of my China photos are out east, so here is a link to a photo showing a barrel with sweet potatoes. The burnt skins don't look that appetizing, but the insides are cooked well enough and nice to eat while walking in cool weather with others: http://www.flickr.com/photos/ajax/3824172/
