There are quite a few in Robertson Quay
I like the book cafe around the corner, but away from the river, got all the magazines you can read, it's been my normal sat hang out brunch place. very chill out, very quiet in comparison to the ones upfront.
However, if you prefer the river view, I also like River Cafe it's at 41 Robertson Quay, a sydney/melbroune type of cafe setting, if you know what I mean I like their salmon bagel. yummmmm
Then there's Cedele, which believe you would have heard it before, it's got one in suntec, one in great wall, one in somewhere orchard....I love their bread, and their spinach mushroom quiche. Although smoothie is done using the fruit flavour milk wouldn't recommend it.
did you mention Epicurious? I haven't tried, but heard about it....
I can go on and on about it, love those bistors, and cafes in the RQ area.....!!!
