There is a cafe on Barrenjoey Road on Newport Beach that makes the thickest, fluffiest pancakes. I love having blueberries in them. Sorry, can't remember the name. InSitu at Manly for beautiful breakfasts. Belgian Waffle Cafe for their waffles and hot chocolate. Also like Cafe Prego in Mosman for their pancakes.
The Boathouse in Palm Beach is one of my favourites. The location and view is excellent, specially if you're able to get a seat outside by the water. It can get quite busy and you have to line up to order your food but it's most definitely worth it for the coffee, as well as their delicious and diverse lunch menu. Ground Zero in Manly is also great for coffee and an affordable breakfast menu, and The Pantry (also in Manly) has quality food and a view that can't be beat (right on the beach front)!
