Jia Jia Tang Bao
Perhaps the most famous purveyors of Xiao Long Bao in Shanghai, Jia Jia Tang Bao is little more than a hole in the wall, but it is an institution in the city. Lines are long and closing times are arbitrary. When they sell out, they close, so try to get there early. The chefs here have mastered the traditional pork filling and even offer crab roe-stuffed Xiao Long Bao.
