They are owned by the same person, according to the staff I spoke to at the Seattle Marrakesh. They also confirmed that the Spokane Marrakesh is owned by someone different, which I know didn't used to be the case because back when I was living in the Spokane area, the owner at the time told me he ran both the Portland and Spokane restaurants, so something must have changed between then and now. The menu is identical from what I remember, right down to design, typeface, and blurbs. Pat
