This review is for the location on Huanghe Road, a few blocks north of Nanjing Road, but each location seems more or less consistent in quality. Sheng jian baozi are a uniquely Shanghai treat, being little buns filled with a very juicy and flavourful pork mince that are fried and steamed, so that they wind up with a delightfully crispy brown base and a light fluffy top. An order consists of four buns, which in my experience is enough to satisfy a craving, but not enough to qualify as a meal (one reason for going to the Huanghe Road branch is that you can treat these as an appetiser, and then continue to Jiajia across the street for xiaolong bao after). There are a limited number of other items on the menu, but sheng jian are the reason for coming here, so why bother with those other things?
One piece of advice--whatever you do, be VERY careful when biting into these little buns! The interior is filled with a scalding-hot mixture of pork and delicious juice, and the juice seems to have a knack for shooting right up your nose if you bite it injudiciously! A good approach is to poke a bit of a hole in the bun so that you can drain out some of the juice, which you can then drink as a soup, but you do want to have a bit of juice with the bun so that you have the full experience. Also, be sure to grab a good number of serviettes, and maybe bring some wet wipes with you.
Service...well, you don't come to a place like this for service, nor for atmosphere. Let's just say that it is what it is, and does not try to be anything else.
