The first thing I will do is go to the Göteborgs Operan in Gothenburg.
The second thing I will do is go to the Pustervik bar/ stage in Gothenburg.
Reasoning
The reason I'm going to both of these places is because I found a list of unique entertainment places in Sweden and I picked these two because I thought they looked the coolest and most interesting.
Price
For the first activity the best tickets are $105.
For the second activity it is free to get in but everything inside cost money so I am budgeting $100.
