For coffee check out Fortitude, Artisan Roast and Cult.
The Bearded Baker does my favourite cinnamon rolls. They normally have three different types and they’re great for a little pick-me-up.
Arthur’s Seat is a classic. You may want to check out The Braid Hills and the Hermitage of Braid walks. The Hermitage is a pretty interesting valley walk with a river and some cool old buildings.
