I've been meaning to visit Jason Bakery for a while now. Eventually the day came, so here's a quick no-frills review:
There isn't a lot of seating, but the bar chairs and tables attached to the outside pillars are actually reasonably comfortable. It was actually genius of them to small half-round tables to the pillars! The croissants are tasty, but the croissant-and-egg breakfast isn't much to write home about (and I was left feeling hungry). Their coffee isn't as good as Origin's, but it's not bad at all (I have a penchant for Origin's flat whites). The staff are friendly and efficient. I'd visit Jason Bakery again, and advise you to do so also! :)
