Restaurants in Chinatown range from casual hawker-style stalls to sit-down dining rooms, and the best way to choose is to look at recent reviews for the dishes and service people mention most. Many diners check whether a place takes bookings, especially on weekend evenings, when the busier streets fill up. It also helps to look at the menu online or on arrival, since prices and dishes can change. Noise levels and seating differ a lot between small venues, so ask for a quieter table if you plan to talk.
