I stayed a few weeks in Robertson Quay. It was hard to find inexpensive brunch options without seating in a huge restaurant / food chain. This was the best option, and it's a great option.
It's owner run. It's small (perhaps room for 40pax ?). It's quiet and relaxed. It's family friendly as well.
Everything seems to be cooked to order. The toasts with nutella and banana are delicious. The hot chocolate is good (that's rare in this country). There is a lot of side dishes options for SGD2-4, which is good if you want to add a little something to your dish without ordering another full place.
The staff is much better than the average in Singapore.
I like this place so much that I take girls on first date there, and they love it.
