Chilli crab. Regarded as a national dish in Singapore, the secret of chilli crab is its thick, messy, sweet, spicy, tomatoey sauce. Egg is often stirred through, making it deliciously gloopy. This is more a trad restaurant than a hawker stall, but they do a mighty fine chilli crab. Where: Roland Restaurant, 89 Marine Parade Central; phone 65 6440 8205.
