The dumplings at Kon Chau send diners into a frenzy. Even when these delectables are too hot to be eaten and too delicate to be seized by a pair of chopsticks, they're sought after. On busy Saturday mornings, packs of patrons gobble down shiny chive shrimp dumplings ($3.75) and crisp taro cakes ($2.95). They hunt down the green tea wrappers packed with slick duck meat and earthy mushrooms that come four to an order because no one can eat just one. They don't forget about the pork pies ($2.95), with savory little nuggets of char siu wrapped inside buttery puff pastry, or the soup dumplings in a slick, meaty broth. After trying this classic establishment, you'll know why crowds go crazy for Kon Chau.
