In the summer this is a haven in the middle of the city. It is a public garden where I like to go and relax in the grass under a blooming tree. There is also a cafe and a shop here. Before you leave you should buy a bouqee of flowers (you pick yourself in the garden!).
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.
