This mee kia tar ($3.80) is definitely one of the best I ever ate. The soup with slices of pork, fish balls etc is also super tasty and is prepared separately by a dedicated staff. The Q is usually long during meal times and so visit the stall in a coffee shop at Fernvale Link, Block 417, Sengkang (opp H2O condo). Bus 163 heading towards Sengkang Interchange will take you there. You may also take the Sengkang LRT and disembark at Layar Station.
