When you visit Gongkee, you will definitely see how small the dinning room is. The restaurant itself looks like it's more setup for take out rather than dine-in. You can order cut meats and take out up at the front.
We have had sit down lunches here before, and the service is great. The orders come in quickly and consistently. It's family owned, so the owners really care about their customers and put a lot of effort with every order.
The food is great as well, although a little oily on their fried food(chicken, squid, etc.). Their Peking duck is awesome and we really enjoy their shanghai/special noodles. My parents regularly order take out from them as well.
I would give Gong Kee 4 stars if their dinning area was bigger and updated. But overall the food is great and the prices are very reasonable. So definitely recommend Gong Kee for take outs, lunches and quick bites for small parties.
