"There's a reason why Kok Sen, perhaps more hawker stall than restaurant, never fails to make it into "best Singapore food" lists: It has a delicious menu of tze char (Chinese homecooked-style fare) dishes. Make a beeline for the signature Big Prawn Hor Fun, flat rice noodles in a gravy cooked for hours with prawn heads so it's rich and briny, then topped with prawns thicker than your thumb. On weekends, there's a special dish of chicken, deboned and stuffed with seafood, that's worth ordering ahead. It gets packed here, but you can make reservations as long as you have six or more people." - Annette Tan
