If you want to try something outside the city center this is a really beautiful small gem. They cook delicious seasonal food and have a nice selection of cheese and charcuterie for your wine. Best to book table beforehand. 

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.

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 

A friendly and relaxed atmosphere with a great kitchen. Lovely music and every now and then surprise live acts as Dungen. A big terrace with the park next door and the new ice cream bar makes it perfect for daytime as well.

Run by a bunch of sound people, VILLA has some great contemporary and affordable art and is always worth a visit.
