Which the best breakfast cafe in Leederville?

Depends on what you want to eat for breakfast really. There is Green and Co. Lots of cyclists tend to go there on a Saturday after their peloton ride. You can get coffee, other drinks and a variety of food. It has papers that you can read and a wonderful atmosphere with lounges and regulars who just love the ambience. It is one of my favourite coffee shops. There is Subway and Reds coffee shop. There is shop that sells sausages in one form or another and I am not sure if the pub is open for breakfast but you could check. Across the road next to Rider's Choice, there is a coffee shop called Cranks and I am sure that you can get food suitable for breakfast from there.
