Went with a party of four Saturday evening about 6:30. Place already packed with families but we were assigned a number and seated after about 20 minutes. Service was prompt and pleasant, food was brought out quickly, and they don't hurry you to leave despite the waiting line outside. The space is attractive, bright and clean.
The specialty, as you can guess from the name, is soup dumplings. Pork soup dumplings were well filled with flavorful pork and a decent broth. They were good but the pork and crab were superb and are a must-have if you like taste of sea. Beef scallion pancake was excellent, a crispy pancake filled with just enough flavorful beef and scallion in a brown sauce. Pan fried pork buns were a trifle bland as was the crispy salted chicken, strips of dark meat that could have been crispier and saltier. Shanghai style udon noodles were savory with bits of pork and baby bok choy.
Definitely worth a second visit.
