I go here all the time. Tiny place but cheap and worth the wait!
Hot and Sour Soup is a must-try! It's definitely one of my favourite spots for cheap food. I love their shanghai-styled noodles. Also, one of the few places that do pan fried styled dumplings (haven't seen anywhere that does them)! Pork and chives is definitely a crowd favourite!
Dumpling types come in boiled (15 pieces) or pan-fried (12 pieces).
