Best choice when you wanna have some local Nanjing food.

“yaxue fensi tang” (duck blood soup, 鸭血粉丝汤) and “tangbao”(soup dumplings, 汤包) are always the best choice when you are hungry and want to have Nanjing local food, and the price is really cheap too, for each are 7 rmb, so for a single person it only need 14 rmb which you will never get this price at other restaurants.
But make sure you get there not right at the lunch are dinner time, coz it will probebly takes half hour to have the soup dumplings since they have too many people and their works do not have enough time to make them.
