At this Flushing restaurant, chef Quiang Wang offers specialties from his homeland. Dig into dishes like hand-pulled noodles in a light lamb broth; steamed soup dumplings; and Big Tray of Chicken, a platter of thighs covered in red chili sauce. In the back room—where Chinese characters for happiness and wealth line the yellow walls—diners can also feast on all-you-can-eat hotpots.
