And the salted egg yolk craze continues... This is not the best I've had, but it's still very good. The salted egg yolk custard filling is thick and rich, sweet and savoury and so, so delicious. I did find the croissant a little too ‘crispy’ for my liking, but otherwise this is pretty decent. Plus, there are no queues here unlike that other place in the same neighbourhood. Do note that Bake Plan has no dining area, only takeaway is available.
