Be prepared to queue even on a weekday. Come at 6pm and expect to wait 15 mins. On Fri/Sat you can probably start queueing from 5:30pm lol. Most Ko-Chi places have the JP+JM+ Tangsuyuk (sweet and sour pork) value set. For 2 pax you will be BEYOND full. 3-pax is about right. This place used to open really late, but now last order is around 10pm~ Top 5 Ko-Chi in Singapore I daresay.
