Best Sushi in Portland?

[petite tête de chou]

Howdy folks. My dad has recently fallen quite ill and has always wanted to try sushi. I ate a fair amount of sushi when I lived in Portland but that was over ten years ago. So I'm hoping someone might have more up-to-date information on where I could get some of the best sushi around. A few things to consider: he is unable to leave his home so I need a restaurant that offers their food to go. I definitely want him to try uni, o-toro/chu-toro, sake harasu (salmon bellies) and, ideally, awabi (abalone). He doesn't have much in the way of teeth so crunchy stuff should be kept at a minimum. Cost doesn't concern me as much as quality. Although I prefer NW Portland since he lives in that area I'm flexible if the sushi is good enough. Thank you so much for any information you can give me. This will really make his day...his week, his year.
