The Book Cafe is an excellent cafe with a decently quiet atmosphere.
On my visit, I put on some headphones and made some progress on my book while listening to reading music. I sat in a sofa area enclosed by book shelves. There are many good reads on the shelves that can be enjoyed with an ice cappuccino.
There are also many desserts to choose from. I ordered the apple pie, it came with a side of chocolate syrup and a few slices of apple. The taste was decent.
This is one of the few public places in Singapore that a book can be read in peace.
