Singaporean Soft Drinks
This one, Sinalco, is apparently Malaysian. It tasted like carbonated Robitussin at first (yuck!), but it grew on me. I guess it's just a pseudo-cherry soda.
Finally, this isn't a drink, but this hawker had a tank of live frogs for food, which was a bit disturbing to me, even though I've certainly enjoyed frog legs before (yes, tastes like chicken).
