I will be going to Portland for the first time ever over Labor Day weekend. I will be staying at the Hotel Monaco in downtown. Does anyone have any must see recommendations/dining/etc. to do while in the city?

Just an overview-I plan to hike outside of the city during the days, and hang out in the city at night, and my last day there, which is 9/1. If anyone has any recommended hikes around Mt. Hood, I'd appreciate that as well. Right now, I am looking at doing Paradise Park or McNeil Point. Any suggested hikes for the Columbia River Gorge are appreciated it as well. I'm pretty fit and am an experienced hiker, so difficulty is not a big issue to me.

Thanks!
