Visited Heng Wah Traditional Coffee, a small stall tucked away in a corner of the sprawling Chinatown Complex Food Centre that had been recommended by JohorKaki. It's easily one of the best kaya toast that I've had - bread toasted to a nice crisp while still retaining a soft spongy interior, light eggy homemade kaya complemented with generous slabs of quality Australian butter, and very affordably priced at $1.40. I love it that it's not too sweet, even though some might gripe that the Kaya fragrance is somewhat muted and overshadowed by the savoury creaminess of the butter. Coffee is pretty good as well: smooth and robust.
