- Chinatown during chinese festivals. Without the festivals, the
place reaaaally screams fake.... pop by the Indian temple nearby,
its worth a look, also has some interesting architecture .. club
street is worth a look at night
- The area around the Arab Street mosque. Also excellent for
hanging out at night, I love Al Tazzag @ Haji Lane, can smoke
Shisha, gorge on mouth-watering dips n kebabs, and sit & chat
at 1 of the outdoor tables along the 2 storey shophouses..
beaut!
- Esplanade/One fullerton area at night (esp when they have events
like National day). One Fullerton has the Merlion.
+
- Fullerton hotel / Singapore River / Boat Quay belt for the unique
architecture and statues (Sir Raffles, Botero's sculptures).. The
area has a very romantic atmosphere in the evenings, check out Boat
Quay's nightlife, also can consider Fullerton's Town Restaurant
(al-fresco) for a lovely dinner by the River.
- Clarke Quay / Mohd Sultan / Robertson Quay area is also pretty
interesting, but mostly only has dining / drinking / clubbing
spots.
- Lau Pa Sat for the food and architecture. Great BBQ stingray n
satay found here 
- East Coast Park, they have a cable water ski park, water sports,
great seafood restaurants.. can consider bringing them around Joo
Chiat for food too if they're up for it.
- MacRitchie Reservoir, an interesting alternative to the zoo. Warn
them not to display plastic bags / food in front of the monkeys
though.
Other than that, can't think of much else a tourist would find
interesting.. :p
