One of your top priorities should be checking out Powells' Books. Amazing bookstore in downtown Portland that you can spend a whole day in.

Portland is also known for having great record stores. If you go downtown you can hit up 360 Vinyl for hip hop on 8th and Ankeny, Jackpot Records on Burnside and 9th, and Everyday Music on 14th and Burnside, west of Powells.

That's downtown. SE portland is a really cool neighborhood too. Check out Hawthorne Blvd. Crossroads music is a great record store there, but very disorganized (part of the fun imo). There are some great restaurants and stores on Hawthorne.

Definitely eat from some food carts. Hawthorne has some good ones and there is also a great pod on 50th and Division, south of Hawthorne. If you like burgers check out either the D48 burger at the Stock & Barrel restaurant on 48th and Division or Little Big Burger on Division and Cesar Chavez.

The Japanese Gardens in NW are beautiful and worth checking out.

Drink a lot of beer. Portland has the most microbreweries (and strip clubs) per capita. I recommend Ninkasi Brewing.

The weather has been amazing lately. Around 80 degrees, sunny and clear which is rare for this time of year and allows a great view of Mt. Hood.

Enjoy your visit, let me know if you want any more suggestions. Portland also has some great restaurants.
