Appreciate the follow-up info!

At the zoo, my kids would be most interested in hands-on things, such as petting or feeding. They're not particularly into monkeys per se. I just brought up Bukit Timah because I figured they'd be interested in seeing wild animals. Thanks for the detailed info. As long as the weather's good and the family's not fatigued from the trip, I think we're going to do the zoo.

ION food court sounds good. We'll also keep Imperial Treasure on our list. Zion food centre is 2km away from Hilton, which is 4x the distance compared to the easily-walkable ION. Based on that and based on what you're saying, I think things like Gardens by the Bay and Zion hawker centre would be options only if time permits. Personally I'd really love to go check out the hawker centre, but the rest of the family might not be keen if there's no A/C, etc.

Are a lot of these spicy? We are really lightweight when it comes to spice. Prawn noodle soups, in particular, look really spicy. Char kway teow looks great, though. Is pho popular in Singapore? In HKG, I sometimes like to have things like roti chennai, sauteed morning glory with garlic, satays and pomelo salad. I've never found those things anywhere outside of HKG (mind you, I've only been to HKG so far in Asia). But I presume all those dishes come from Malaysia or Singapore. Do you think the food court might have some of those things?

Anyways, I'm sure there will be no shortage of great food that the whole family will love.
