This windowless dim sum lounge looks small from the outside, but there’s room for over 100 diners inside its cherry-red dining room—with dozens more hopefuls lined up on the street outside. The largely Chinese crowd attests to the authenticity of the food, which ranges from steamed pork buns and taro dumplings to chicken feet with peanuts and Peking duck—if you’re hoping to skip out on the wait, go at dinner instead of lunch, or call for takeout. Favorites include rice noodle rolls stuffed with ground beef and aromatic herbs and crispy, golden pan-fried tofu with a silky interior. Shanghai pork soup dumplings arrive in a steam basket in individual metal cups. Served with black vinegar for dipping, they're achingly fragile but terrifically tasty.
