We went to Sentosa via the free shuttle service provided by Genting Jurong Hotel to have our family dinner. We purchased a voucher via Klook for the Good Old Days Restaurant Buffet Dinner, we choose this since they are located at the Siloso Beach Front in Sentosa Island which is the location of our next destination which is the Wings of Time.
There is no need for reservation but you need to exchange your Klook voucher to a ticket in the kiosk which is just outside the restaurant. The process is really quick and afterwards we proceed to our dinner.
We somewhat enjoyed our dinner since we are all together but we do not recommended going to this place. Maybe if you purchased the same voucher you can try the lunch at Faber Peak instead of the dinner buffet.
