Question What to Do in Goteborg in Two Days?

Hi, we will be traveling to Goteborg mid-September. We will spend three nights and two full days there and are looking for recommendations on what to do. We're interested in a mix of cultural experiences, local food, and maybe some outdoor activities if the weather permits. Any must-visit spots or hidden gems we should check out? Also, any tips on getting around the city would be helpful. Looking forward to your suggestions!
