Shopping is my favorite activity, also like anything to do with animals. Love restaurants, pasta, steak, sushi,.
We have a great zoo here, which is not far from downtown.
Portland is loaded with great restaurants! My all-time favorite is Habibi in downtown Portland. It's Mediterranean and the food is fabulous! Plus the owner is very nice and not too bad on the eyes! LOL
On the weekends until Christmas, there is the Saturday Market downtown. It's local artisans selling their stuff. You can get some cool things there and the people-watching is rather entertaining! You're bound to see 'Elvis' wandering about.
Hmmm...for other restaurants....Pasta...Pazzo in downtown on Broadway comes to mind..steak...there's Ruth Cris, Morton's Steak House, El Gaucho (that one is rather expensive, though...sushi....I don't do sushi so I have no clue! LOL Oba is fabulous (have a mojito for sure!)...oh my...Portland is just loaded with great restaurants and little clubs. There is Caprial's (from PBS).
Are you staying in a hotel? They'll have lots of good ideas. I'm sure there will be holiday things going on.
I could think of more (and more specific) if my poor old brain wasn't all befuddled with a cold! LOL
Ohhh! One more shopping place...
Nordstrom Rack in downtown Portland.
