If you go to Singapore, you must try the famous black pepper crabs. Not that I am suggesting you flying 15 hours, half way around the world, just to try it. But if you are town, go for it. They taste great. Hot, spicy and fresh. If you cannot stand spicy food that definitely do not try this. If you cannot eat hot food, why are you in Singapore?!
I ate at the Long Beach restaurant. Thi is the standard restaurant for all sorts of seafood. There are three of Long Beach restaurants. The main one is at the East Coast area at the Tennis Center. Just Ask. Taxi driver will know.
Oh, don't forget the Sugar Crane Juice and Oyster Omlette
