Singapore

Singapore is a beautiful, clean, efficient little island. While it's true that you cannot have gum anywhere in the city or eat on the public transportation, this leads to a very pleasant subway (MRT) system. Everything is air-conditioned and connected underground. Though it may seem like a strange recommendation, I'd say check out the malls. They are huge and have great food. I have gotten so lost in a mall that I didn't even know if I was above or below the ground. The turtle garden a little west of Jurong East is also worth a visit.
