Not too sure why, but the liu sha bao here has great resemblance to the ones over at The Bosses Restaurant, on level 2 also at Vivocity. The colour and texture of the buns, how soft and airy they are. The colour of the salted egg yolk custard, its oiliness that leads to the ooziness, and how it leans towards the saltiness of the salted egg yolk instead of some that are more milky and sweet. Also, the sandy texture of the custard. Everything's so similar!
