During the summer Trädgården is the place to be if your out clubbing. It has a great festival atmosphere. The chance of you getting seperated from your friends is immidiate but you will meet new ones. I have a love-hate relationship with this place, watch out for the massive que and the ill willing pointers.
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.
