I love food. And I love Singapore.
Yes, there’s more than just Chicken Rice that you’ll love in this country. It’s the place for all salted-egg-flavored food, creamy chili food, curries, duck rice and the most affordable breakfast staple – the “economic beehoon” and lunch – the “economic rice”.
It’s that delightfully exquisite common food – hence “economic” – of rice or beehoon layered with your choice of fish cakes and other dishes, soaked with the shop’s signature yellow curry sauce, topped with your preferred amount of ‘sambal’ chili, wrapped in brown wax paper bound by a rubber band and carried in a small plastic bag, hence the “packet”, “tapao” or “takeaway” food. These were not introduced to me when I was a tourist. And it can be as cheap as S$3.50 for 1 meal.
Personally, I drool over anything wrapped in brown wax paper. Like the briyani rice with a quarter chicken leg or the falling-off-the-bone mutton with papadums. It always goes well with Teh Tarik. 
And where else can you get your “kopi” in a plastic bag with a straw? (Very similar to how we buy softdrinks in sari-sari stores back home)
Kopi : the basic version is hot brewed coffee with condensed milk and sugar
Kopi-O : 1:1 blend of coffee and water plus 1 teaspoon of sugar
Kopi-O Kosong : “Kosong”means “empty” in Malay. So this is just equal parts of coffee and water, no sugar
Kopi-C : 3:2:1 blend of coffee, water and evaporated milk. Take note that “C” in Kopi-C stands for “Carnation”
Kopi-siu-dai : “Siu Dai”is Hokkien for “less sweet”. 1:2 blend of coffee to water, paired with condensed milk and a dash of sugar.
