Came across the place after buying gifts at the MyOne Shop nearby. 6PM and the smell of caramelized onions piqued my interest. Ordered a simple beef-mayo-egg burger with no chili sauce, and was blown away by the quality. Tasty, juicy with the right char. Amazing ramly-style burger but so much more sophisticated. 

Found other stalls of Otai at TTDI jasima and Plaza Damansara, but the KJ one is the best. 

Speso also recommended, it's a thicker more premium patty. Will try the wagyu, next
