We came for lunch around noon and there were about 5 people in front of us. We waited less than 5 minutes.
The place is cramped and most likely you will have to sit next to a stranger.
We ordered the BBQ pork/goose rice (60 HKD) and BBQ pork noodles (62 HKD). Food came right away and we ate and left. They take cash only.
Also, don't expect any water or additional service. The expectation is you eat and leave.
Food is good but not the best BBQ pork I've had. Mott 32 had better BBQ pork.
