About twice a year for several years now, a friend from Seattle comes down to Portland for the weekend, and a bunch of us always get together to have brunch here, located by the water on River Place. Thus, I can personally vouch for this venue. For quite awhile now, I have been wanting to organize a brunch here for ACJ, and have finally gotten around to it.
The cuisine here is of above-average quality, and portions are generous. A good selection of breakfast and lunch items is available. You can peruse the menu here: http://www.threedegreesportland.com/
We will have separate checks. Come and join us for the fun.
