Singapore can be done in a day and a half. The best thing to do is to stay in Little India and visit Chinatown.
In Chinatown, visit the Buddha Tooth Relic Temple and Museum just down the street from the Sri Mariamman Temple (Hindu), which isn’t far from the Jamae Mosque (Muslim). That’s Singapore in a nutshell – a harmony of cultures.
At the Buddha Temple go upstairs to the free Buddhist museum on the 3rd floor. They have tons of Buddhist relics from around the world and have done a good job telling the story of Buddha in a designed path through the museum. Take your time. Read a bit. Learn a bit.
Then hit up the stairwell and sneak up to the roof. You’ll find a lush rooftop tropical garden surrounding a large Buddhist prayer wheel. Grab the wheel, walk in a circle and make a prayer. It’s okay. You’re allowed to be there.
For lunch, go behind the museum to the Chinatown Complex (food hawker center). There are 1,000 food stalls. Take a deep breath and find a stall that sells ‘chicken rice’. When I was there it was #172. It should cost S$3. Wait for it. Make sure to take the little tray of red sauce. The dish will look bland – you will be surprised.
