Over at Paper Rice Vietnamese Kitchen, they use a secret recipe for the egg froth to produce the creamy froth, as well as imported Vietnamese milk to complement the dark coffee.
Service at Paper Rice Vietnamese Kitchen is passable, and uniquely Singaporean.
It had a nice char-grilled aroma and skin that went nicely with a dip in that brown herbal salt mixture, making for a decent deal at only S$18.80 (US$13.90).
I've ordered these too many times and I guess that does say something for the boring folks - good and consistent enough.
