Food is an obsession in Singapore, and eating here is like a sport. When Singapore's king of hawker food, K.F. Seetoh, takes you on a food crawl, you know you're in for a serious challenge. Our first of 5 food center stops was Old Airport Road hawker center for the prawn noodle soup (studded with cuts of pig's tails that are eaten like corn on the cob) at stand #01-98, Whitley Rd Brig Prawn Noodle.
