Cre Asion is one of my favourites for macarons in Sydney (up there with Baroque / La Renaissance at The Rocks). I love the Japanese-influenced flavours like miso, yuzu and green tea, but the staples like Dear Chris (chocolate and hazelnut), dark chocolate and passionfruit are crowd-pleasers.
They do great cookies and I actually like them more than the macarons. Try the dark salted chocolate cookies. They're just the right amount of crumbly and they aren't too sweet.
They do great lunch sandwiches which are really tasty but a little messy to eat.
The owner and staff are really lovely and take great pride in their work. Watch them assemble sandwiches with great care but save it for a time when you're not in a hurry and don't need to zip in and out.
Great little cafe - they deserve to do well!
