Dumplings are one of my comfort foods, and they make some really delicious steamed dumplings here. I usually go for the juicy pork bun dumplings and then either shrimp or tofu dumplings (steamed, not boiled), for a little variety.
They also sell frozen dumplings that you can boil at home. They're more expensive than the mass-produced frozen dumplings you can buy at the supermarket, but the ingredients are superior and the shells are thicker.
