A 500-meter long (quarter mile) walking path with a magnificent view of Lake Mälaren, City Hall, and Riddarholmen. Bring your take-away coffee and walk the path at least once every season to notice the different scents and colours of Stockholm.
It's been at the same address for the last 80 years apparently and serve some classic swedish food like köttbullar and isterband. Being swedish I guess could I either avoid or cherish this, but I choose the latter.
This is my favourite café/workspace place. The staff is super friendly and competent. The space has a nice interior and you can order a coffeepot and stick around for a while. In the warm months you can enjoy sunbeds outside
