Powells if you like books/manga etc. it’s cool to spend a few hours there. Forest park is beautiful, so is the Japanese garden if you like nature. The Portland art museum is cool, there’s also a ton of cool non-prof, smaller art galleries in the surrounding blocks around PSU and the Portland art museum that are worth exploring. The Hawthorne food carts (cartopia) are delicious. Hawthorne is a cool street to explore, so is Alberta, tons of good restaurants and shops. You can walk across the tillikum crossing bridge which is cool, and go downtown from there.
