Also, for those that have never had a soup dumpling before, here's a quick description:

Xiaolongbao are traditionally filled with pork, but variations include other meats, seafood and vegetarian fillings, as well as other possibilities. One popular and commonly seen variant is pork with minced crab meat and roe. The characteristic soup-filled kind are created by wrapping solid meat aspic inside the skin alongside the meat filling. Heat from steaming then melts the gelatin-gelled aspic into soup.

It's basically an inside out dumpling soup. You bit off a side of the dumpling, then suck out the delicious soup inside. I can't overstate how wonderful this is.
