If there is one food item that is easiest to find in Sim Lim Square apart from the usual economical rice stalls, then it would be Salted Egg Yolk Chicken Rice.
A good alternative to Taste Good and The Rice Bowl's Buttermilk Chicken Rice (because its always so crowded during lunch hours), the Mini Wok stall at Broadway Food Court at the basement is also one that satisfies those cravings. Featuring chunks of fried chicken drenched in that creamy yet saltish sauce, it also carries a slight sweetness that helps to balance things out a little for that sweet-savoury note. Coming with crisp curry leaves and chili padi, these enhances those flavours even further by adding a contrast with its fragrance and mild spiciness. No doubt this version does not come with as much sauce as some other places does to allow one to just slather it all over the rice, nor does this variant feature actual chunks of salted egg, but this is a variant that does well enough to satisfy those cravings whenever it hits.
