Well, you got all the answers in the tourist books already, but if you want to see the real Singapore you have to get away from tourist locations - but that of course depedns what kind of traveler you are. The key event in Singapore is on Feb 3rd, the Tamil Hindu festival of Thaipusam which is spectacular to watch ... Regarding food, try eating like the locals - the Boat Quay and so on are all expensive and for tourists, and to be honest, not that great. Maybe try hawker centers around Geylang or any other area you find yourself in. A favorite out of town in the West is the Big Eater Seafood Restaurant, Blk 964 Jurong West Street 91 - closest MRT is Pioneer, or go by taxi. Have fun ....
