A friend in Hong Kong brought us to this place. So I will only try to recount the way we went to this very famous restaurant. There are of course other ways, I am sure. As the place is near the Hong Kong Happy Valley Racecourse, it is really not hard to find :)
We were shopping at Causeway Bay before dinner so I am guessing you can take the MTR to Causeway Bay and follow the way we went. Alternatively, because we were also taking the Ding Ding Tram from Causeway Bay to Happy Valley, you could hence get on to a Ding Ding Tram stops in Central Hong Kong. However, take note that only 1 service goes to Happy Valley route which I think is the BROWN line. Check the web site here for details. It is important to take note that only 1 service goes that way.
Anyhow on that day, we took the Ding Ding tram (HKD 2 per person only!) from Causeway Bay to the Happy Valley Bus Termius. You know this is the final stop as everyone gets off. From there, it is a 5 minute walk to the Gi Kee seafood restaurant. We saw very nice condos there at Happy Valley and many expatriates. Our friend told us that Happy Valley is a very popular place with expatriates (And the stupid me thought every expatriate stays at Mid Levels or the Peak :p)
The store is situated inside a market type of hawker centre (reminds me of those in Singapore). So it is not exactly a restaurant but a hawker store. The tables and chairs are exactly like Singapore :p
When you take the lift up and the lift door open, be prepared for a shock. No.. kidding. Two person will ask you which restaurant to go to. You just need to say “Gi Kee” if you are going there. The other store is Sheung kee. They are two different stores operating at the same place, sharing the same place and fight fiercely for customers ! :)
Look at the colours of the plastic table covers. The orange is for Sheung Kee and the white one is for Gi Kee !
